Abstract: Biasing of radio frequency (RF) switches for hot switching is disclosed. In certain implementations, an RF switch includes a first series switching circuit connected between a first pole and a first throw and a second series switching circuit connected between the first pole and a second throw. Additionally, a control circuit controls the first series switching circuit with a first switch control signal and the second series switching circuit with a second switch control signal to provide a transition of the RF switch from a first state in which the first series switching circuit is turned on and second series switching circuit is turned off to a second state in which the first series switching circuit is turned off and the second series switching circuit is turned on. The control circuit turns on the second series switching circuit before turning off the first series switching circuit when providing the transition.

Abstract: An embodiment of the present invention includes a master camera that may record master metadata regarding an object of interest and communicate the master metadata to a slave camera. The slave camera may zoom, pan, or tilt to isolate and record more detailed image data regarding the object of interest based on the master metadata. In addition, the slave camera may record slave metadata regarding the object of interest. The master and slave metadata may be stored associated with the recorded image data enabling a later search for the object of interest to be expedited. The recorded image data including the object of interest may be identified with greater ease as it may be guided by the master or slave metadata, or a combination thereof. According to embodiments presented herein, processing time for searching and identifying an object of interest may be reduced by enabling a search on the metadata associated with image data, rather than by searching the image data itself.

Abstract: Network cameras employing advanced video analytics are increasingly being used in both public and private settings. Unlike fixed surveillance cameras, pan/tilt/zoom cameras provide a dynamic field-of-view. Some regions within a given field-of-view can be designated as private and may not be recorded. A window-blanking feature, according to an embodiment of the invention, enables an ability to block out defined portions of the video where a privacy zone may otherwise appear. Through use of the embodiment, consistent privacy is provided during dynamic surveillance to ensure compliance with privacy regulations or contractual arrangements relating to use of a surveillance camera having a privacy zone within the given field-of-view.

Abstract: An approach is provided for determining context-based groups based on context information. An input from a device specifying one or more criteria to determine a context-based group from among a plurality of other devices is received. The context information associated with the plurality of other devices is determined. The context-based group is determined based, at least in part, on the context information and the criteria.

Abstract: Disclosed are novel isoflavone derivatives having the structure of Formula I which are useful as ALDH-2 inhibitors for treating mammals for dependence upon drugs of addiction, for example addiction to dopamine-producing agent such as cocaine, morphine, amphetamines, nicotine, and alcohol.
