Methods and apparatus for detecting false alarms are disclosed. An indication may be received that a sensor device has changed state. Data indicative of movement of the sensor device may also be received. Based on the received data indicative of movement of the sensor device, it may be determined whether the movement of the sensor device is abnormal. Based on the changed state of the sensor device and based on determining that the movement of the sensor device is abnormal, an indication of a false alarm may be caused to be output.

Methods and apparatus for detecting false alarms

An apparatus, such as a doorbell, may include a doorbell housing. The doorbell housing may include a front surface facing exterior of a premises and a rear surface facing interior of the premises. A camera, doorbell activator, motion sensor, and/or light source may be at least partially positioned within the doorbell housing. An antenna may be positioned within the doorbell housing. The antenna may be configured to send a wireless signal comprising data to a data receiving device inside the premises. A reflective member may be positioned within the doorbell housing and configured to reflect at least a portion of the wireless signal that is sent toward the front surface of the doorbell housing.

Video device with electromagnetically reflective elements

A multiway switching device may comprise a wireless device in communication with a relay and a manual switch of the device. A toggle state of the relay may be indicative of an electrical configuration between conductors and rectifier circuits of the multiway switching device. The wireless device may receive, from the manual switch or from an external device, a signal indicative of a modification to the toggle state of the relay. Based on the signal, the wireless device may cause the modification to the toggle state of the relay. The wireless device may cause output of a status signal indicative of the modification to the toggle state of the relay.

Three-way switch

A system may comprise a sensor device. The sensor device may be configured to determine a received signal strength indicator (RSSI) of a signal received from another device. The sensor device may be configured to determine, based on the RSSI and a sensitivity threshold, a transmission power level. The sensor device may be configured to send a second signal using the determined transmission power level.

Adaptive power modulation

Devices and methods comprise a relay coupled between conductors and rectifier circuits. A converter is coupled between the rectifier circuits and a radio frequency (RF) device. Control signals are coupled to the RF device. A physical switch is coupled to the RF device, and the control outputs of the physical switch form a multi-way switch.

Systems and methods comprise determining a received signal strength (RSSI) of a signal. A sensitivity level of a receiver is determined, where the signal is to be received at the receiver. When a determination is made that the RSSI is greater than the sensitivity level, a transmitter power level is calculated as a difference between the RSSI and the sensitivity level. A transmitter of the signal is controlled in accordance with the transmitter power level.

Adaptive Power Modulation

A method and system is disclosed for spreading the power associated with digital signals being transmitted to reduce electromagnetic interference (EMI) emissions by receiving, via a first transmission line, a first power spread signal representative a first digital signal modified using a first power spreading digital noise signal, modifying the power spread signal using a second power spreading digital noise signal substantially similar to the first power spreading digital noise signal to generate a second digital signal substantially similar to the first digital signal, modifying the second digital signal using a third power spreading digital noise signal to generate a second power spread signal and providing the second power spread signal for output to a second transmission line.

Reduced EMI device and method thereof

A method and system is disclosed for spreading the power associated with digital signals being transmitted to lower electromagnetic interference (EMI) emissions. After being transmitted across a transmission line, a representation of the original digital signal is recovered and provided to a destination device.

Method and system of reducing electromagnetic interference emissions

A method and apparatus for generation of pixel lookahead information in a cached computer graphics system is provided. For each pixel-based memory operation, several data items may be generated, such as numerical values representing a coordinate point in an image coordinate space or display coordinate space and characteristic data representing a color value or depth value for the pixel. In addition, lookahead data correlated with the coordinate data is generated. The pixel operation is then issued with the characteristic data, the coordinate data, and the lookahead data. The lookahead data may contain a lookahead vector, which specifies a lookahead vector direction and a lookahead vector length, and a lookahead valid flag, which indicates whether associated lookahead data is valid for the pixel operation. The lookahead direction may be computed based on the coordinate data of the pixel operation and coordinate data for a pixel operation to be performed within a threshold number of pixels operations from the pixel operation. By providing lookahead information based on the rendering state of the graphics subsystem, pixel operation intentions may be indicated prior to the issuance of a pixel operation so that the pixel data may be prefetched into a cache.

Method and apparatus for lookahead generation in cached computer graphics system

A method and system for an approximation of a filter function for computing a characteristic value of an output pixel based on characteristic values of a plurality of input pixels is provided. A filter response curve adjustment value is obtained, preferably from a lookup table, based on a distance interval between coordinates of the output pixel and coordinates of a selected input pixel. A normalized filter response curve input value is computed based on the distance interval and the filter response curve adjustment value, preferably by adding the values together. The characteristic values at a plurality of input pixels are obtained. A linearly interpolated value for the characteristic value of the output pixel is then computed based on the characteristic values of the plurality of input pixels and the normalized filter response curve input value.

Method and system for filter type approximation in computer graphics processing

A cache replacement algorithm improves upon a least recently used algorithm by differentiating between cache lines that have been written with those that have not been written. The replacement algorithm attempts to replace cache lines that have been previously written back to memory, and if there are no written cache lines available, then the algorithm attempts to replace cache lines that are currently on page and on bank.

System and method for cache line replacement

To reduce the performance penalty associated with frame buffer memory access times for each page when rendering a primitive having scan lines which cross page boundaries, rendering is constrained to a single page at a time. All pixels mapping to a currently-cached frame buffer page are rendered before loading a different frame buffer page into the cache in order to render other pixels within the primitive. Any pixels within a scan region which map to a different page than the active page are temporarily skipped until all pixels mapping to the current page are completed. Only when no more pixels require rendering within the primitive which map to the currently active frame buffer page is another frame buffer page loaded and all pixels mapping to that page are rendered. In processing a scan region which crosses a page boundary, the next pixel or pixel group to be rendered is examined to determine if it maps to the currently active frame buffer page. If so, it is rendered; if not, however, the position is latched, together with any other necessary state information, and rendering proceeds with the next scan region. Once all pixels for a currently active page are rendered, the latched position is loaded, together with the frame buffer page necessary to render the corresponding pixels, and rendering of the primitive proceeds until complete.
