An apparatus, computer program, and method are provided for utilizing a particular radio access technology to connect to a telecommunication network before an expiration of a timer. A wireless communication device is provided including at least one hardware processor configured for sending a first request from the wireless communication device for connecting to a telecommunication network via a first base station for a first area. Such first base station implements a first radio access technology that has a first priority and a first data rate. In response to detecting a failure of the first request, a second radio access technology is utilized to connect to the telecommunication network before an expiration of a timer. Such second radio access technology has a second priority that is lower than the first priority and a second data rate that is lower than the first data rate. Further, in response to detecting that the wireless communication device has moved to a second area associated with a second base station before the expiration of the timer, a second request is sent via the second base station that implements the first radio access technology for utilizing the first radio access technology to connect to the telecommunication network before the expiration of the timer.

Apparatus and method for utilizing a radio access technology to connect to a telecommunication network

Disclosed are methods and apparatus for utilizing any of a plurality of disparate types of lens actuators on a mobile device. The method may include launching a configurable actuator driver and identifying a particular type of lens actuator that resides on the mobile device. Based upon the particular type of lens actuator that resides on the mobile device, lens-actuator-specific parameter values are obtained that facilitate control interfacing with the particular type of lens actuator. In addition, tuning parameter values are obtained that characterize a displacement-response of the particular type of actuator to control signal values, and the tuning parameter values for the particular type of lens actuator are provided to a configurable lens-actuator driver. The particular type of lens actuator that resides on the mobile computing device is then operated using the tuning parameter values.

Configurable lens actuator driver system

Described herein are methods, apparatus, and computer readable medium to autofocus a lens of an imaging device. Parameters are received indicating a lens position. Lens actuator characteristics are determined. Lens damping parameters may be determined based, at least in part, on the input parameters and the lens actuator characteristics. In some aspects, lens damping parameters include a lens movement step size and a time delay between each step. In some aspects, the lens damping parameters include damping parameters for a plurality of regions of lens movement. Lens movement parameters are determined based, at least in part, on the input parameters and the lens damping parameters. The lens is then autofocused by moving it according to the lens movement parameters.
