Apparatuses and methods for detecting an obstacle in a path of an Unmanned Aerial Vehicle (UAV) are described herein, including, but not limited to, receiving data from a single image/video capturing device of the UAV, computing a score based on the received data, and performing at least one obstacle avoidance maneuver based on the score.

Apparatus and methods for low power sensing of wireless access technologies are disclosed. In particular, a mobile wireless device, such as an access terminal, may utilize a lower power circuitry portion that operates at a lower power than active circuitry, such as a primary transceiver. The lower power circuitry portion includes a configurable searcher that is capable of sensing if signals of one or more various wireless access technologies are present. When the wireless device utilizes sleep or idle modes for power savings, use of the lower power sensing circuitry to sense the presence of wireless access technologies, rather than using an awoken higher power primary transceiver for sensing, affords increased power savings. An added ability of the lower power circuitry to be put into sleep or idles modes achieves even greater power savings.

Apparatus and methods for low power sensing of communication access technologies

A method and an apparatus for system acquisition at a wireless device while maintaining a predetermined battery life span, include determining a level of remaining battery power upon entering an out of service state. A duty cycle, comprising a search time and sleep time, of acquisition attempts is determined such that the level of remaining battery power lasts for the defined battery life span. The duty cycle is determined by adjusting at least one of the search time and the sleep time, depending on how long the remaining battery power is required to last.

A multimode wireless communication device utilizes location information provided by a co-located autonomous position location receiver to determine a preferred provider database and associated operating mode and operating technology when an out-of-service condition is encountered. The multimode wireless communication device can utilize active preferred provider database while in service and while acquired within a network. The multimode wireless communication device can initiate location-based mode and technology control when in an out-of-service condition. The multimode wireless communication device determines its location and based on the location, accesses a database to determine a preferred provider database. The preferred provider database provides a hierarchical list of available systems and associated information for acquiring and registering with the systems. The multimode wireless communication device reduces a search time and associated power consumption using location-based mode and technology control.

An apparatus and method for identifying a serving country using at least one system specific parameter comprising extracting the at least one system specific parameter from a forward link signal; determining whether the at least one system specific parameter maps to a unique country; and identifying the serving country for a call.

An apparatus for detecting the presence of a frequency channel is provided. The apparatus comprises an energy detection unit configured to measure receive energy over a first bandwidth and a second energy detection unit configured to measure receive energy over a second bandwidth. The apparatus further comprises a processor configured to compare the measured receive energy over the first bandwidth to a first energy threshold, to compare the measured receive energy over the second bandwidth to a second energy threshold, and to detect the presence of the frequency channel when the measured receive energies over the first and second bandwidths are above the first and second energy thresholds, respectively.

An apparatus and method for a centrally managed handoff comprising originating a service using a first technology and connecting the service using the first technology; activating a second technology that is different from the first technology; receiving a first request for the handoff from the first technology to the second technology; sending a second request for the handoff from the first technology to the second technology, wherein the second request relates to the first request; receiving an acknowledgement that the second technology is available; implementing the handoff from the first technology to the second technology; and determining that the handoff is successfully implemented before terminating the first technology.

Disclosed are systems, methods and computer program products for better system reselection (BSR) in a multi-system wireless communication environment. In one aspect, the BSR procedure provisions a mobile device to determine if a currently-registered wireless communication system is the most-preferred system among systems of a similar technology and among systems of different technologies identified in the device's combined preferred roaming list (PRL). The mobile device then activates an intra-system BSR timer if the currently-registered system is not the most-preferred system among systems of similar technology and an inter-system BSR timer if the currently-registered system is not the most-preferred system among systems of different technologies. Upon expiration of the intra-system BSR timer, the mobile device searches for a more-preferred system among systems of similar technology. Upon expiration of the inter-system BSR timer, the mobile device searches for a more-preferred system among systems of different technologies.

A method and apparatus for channel acquisition using a mobile station include obtaining geographic information of at least one wireless communication systems using one or more systems, respectively. The one or more channels are prioritized on a preferred roaming list based on the geographic information, and it is determined whether any of the prioritized one or more channels on the preferred roaming list are also on a most recently used (MRU) list. The mobile station attempts to acquire at least one of the prioritized one or more channels that is also on the MRU list.

Method and apparatus for channel scanning that improves acquisition probability and power consumption

Techniques to search for signals while in an out-of-service state are described. In an aspect, a network entity may collect information for wireless devices within a designated area, determine at least one search parameter (e.g., a scan rate) based on the collected information, and provide the search parameter(s) to wireless devices within the designated area. The wireless devices may perform searches for signals in accordance with the search parameter(s) when they are out of service. In another aspect, a wireless device may collect information related to out-of-service events encountered by the wireless device, send the collected information to the network entity, receive the search parameter(s) from the network entity, and perform searches in accordance with the search parameter(s) when out of service. In yet another aspect, the wireless device may determine the search parameter(s) based on the collected information.

A channel scanning order is dynamically created, modified, selectively ignored, or combinations thereof based on historical data, motion information, context information, alert message systems, network reselection, or combinations thereof. If a less preferred network has served a mobile device longer than a threshold amount of time, acquisition of the less preferred network is attempted before attempting acquisition of a more preferred network.

Methods and apparatus for out of service processing with varied behaviors. In an aspect, a method is provided for service acquisition. The method includes determining one or more conditions, wherein each condition is associated with at least one weight, detecting whether an out-of-service event has occurred, and if an out-of-service event is detected: identifying selected conditions and associated weights, and processing the associated weights to determine service acquisition 'on' and 'off' times. In an aspect, an apparatus includes condition logic configured to determine one or more conditions, wherein each condition is associated with at least one weight, and processing logic configured to detect whether an out-of-service event has occurred, and if an out-of-service event is detected, to identify selected conditions and associated weights, and process the associated weights to determine service acquisition &#x201c;on&#x201d; and &#x201c;off&#x201d; times.
