| 20120131219 | Systems and methods for media stream processing - Portions of streaming media are selectively removed for storage and/or delivery over a computer network medium. The amount of data in a media stream itself may be selectively reduced for and, the amount of data in the media stream may be selected for delivery and/or storage so that it is reduced in a manageable and consistent fashion. Data within a media stream of a given temporal duration may be selected for delivery and/or storage in such a way that leads to a proportional increase in the maximum speed at which data from the given temporal duration of the media stream may be transmitted and reviewed while simultaneously providing the benefit of reducing overall storage capacity requirements. | 05-24-2012 |
| 20120126936 | Access control system - An access device for a system having at least one lock that is configured to receive instructions and to energize a lock mechanism to unlock the at least one lock and a computer is disposed at a remote location from the at least one lock and the access device. The computer is connected to a primary wireless communication path. The access device comprises at least one key configured for communicating with the computer via the primary wireless communication path and to communicate with the lock over a secondary wireless communications path and wherein the at least one key further is configured as authorized to unlock the at least one lock absent a de-authorizing instruction from the computer. | 05-24-2012 |
| 20120055235 | Carbon monoxide detector, system and method for signaling a carbon monoxide sensor end-of-life condition - A CO detector includes a sensor configured to detect a presence of CO and generate a signal indicative of the presence of CO, and a controller in signal communication with the sensor. The controller is configured to measure a level of detected CO in response to receiving the signal generated by the sensor. The controller is further configured to detect a first trouble condition representative of an end-of-life condition of the sensor, and a second trouble condition different from the first trouble condition. | 03-08-2012 |
| 20110292287 | Systems and methods for multi-stream image processing - Systems and methods for the processing of images over bandwidth-limited transmission interfaces, such as processing of high resolution video images over standard analog video interfaces, using multi-stream and/or multi-resolution analog methodology. The disclosed systems and methods may also be implemented to provide video resolutions across standard analog video interfaces in a manner that supports digital capture and imaging techniques to obtain useful information from digitally zoomed and enhanced video. | 12-01-2011 |
| 20110287803 | Wirless security messaging model - Reducing power consumption and interference in wireless communication is provided. For example, in one embodiment, a method is provided that listens for radio frequency (“RF”) activity on a receiver utilizing a first receiver antenna. When no RF activity is detected the receiver is switched “on” and a command is transmitted. If a reply to the transmission is not received the receiver is turned “off.” After an expiration of time, the receiver is again switched “on” and another command is transmitted on a second antenna coupled to the receiver. Thereafter, if a reply is not received the receiver is again turned “off.” Embodiments of the invention also include other methods, computer-readable mediums, apparatuses, and systems that contain features similar to the features in the above described method. | 11-24-2011 |
