Abstract: A single silicon wafer micromachined thermal conduction sensor is described. The sensor consists of a heat transfer cavity with a flat bottom and an arbitrary plane shape, which is created in a silicon substrate. A heated resistor with a temperature dependence resistance is deposed on a thin film bridge, which is the top of the cavity. A heat sink is the flat bottom of the cavity and parallel to the bridge completely. The heat transfer from the heated resistor to the heat sink is modulated by the change of the thermal conductivity of the gas or gas mixture filled in the cavity. This change can be measured to determine the composition concentration of the gas mixture or the pressure of the air in a vacuum system.

Abstract: A support base for a child safety seat includes a shell body, an adjustable arm assembled with the shell body and having a rear end provided with a fastener operable to attach with an anchorage fixture of a vehicle, a safety lock, and a coupling portion assembled through an interior of the adjustable arm. The shell body is movable along the adjustable arm to adjust a distance between the fastener and a rear of the shell body. The safety lock is assembled with the shell body, and includes a latch operable to engage and disengage an opening of the adjustable arm. The latch is operable to lock the shell body with the adjustable arm, and a locking engagement of the fastener with the anchorage fixture causes a displacement of the coupling portion that pushes the latch to disengage from the opening for allowing displacement of the shell body toward the fastener.

Abstract: A cascadable camera tampering detection transceiver module has a processing unit and a storing unit, an information controlling module and an analyzing module. The storing unit stores a transceiving module. The detection module analyzes input video, detects camera tampering events, synthesizes the input video with the image of camera tampering result, and outputs the synthesized video. When the input video is an output from the detection module, the detection module separates the camera tampering result from the input video, and the result can be used to simplify or enhance the subsequent video analysis. Performing the existing analysis repeatedly may be avoided, and the user may re-define the detection conditions in this manner. When the camera tampering result is transmitted in the video channel, the detection module transmits the camera tampering result, and hence the detection module may be used in combination with surveillance devices having image output or input interfaces.

Abstract: An interconnect module for communicating electrical signals and optical signals is described. In particular, an integrated circuit in the interconnect module receives and transmits the electrical signals with other components in a system that includes the interconnect module via an electrical connector. In addition, the integrated circuit receives and transmits electrical signals to a hybrid silicon-photonic bridge chip that performs electrical-to-optical and optical-to-electrical conversion. In turn, this bridge chip receives and transmits optical signals via an optical fiber. The interconnect module can be remateably connected to a backplane in the system, and can be arranged in a stacked configuration with other instances of the interconnect module. In these ways, the interconnect module facilitates dense, modular or scalable, and compact electrical and optical communication in the system.

Abstract: In one embodiment, source data for a communication session may be split into an audio portion for transmission on a phone channel and a non-audio portion for transmission on a data channel. A server and a phone may accordingly establish an audio portion of a communication session on the phone channel. In response to a trigger, the server may provide a push notification on the data channel to the phone, where the push notification is associated with an application executing on the phone that is configured to participate in the non-audio portion of the communication session on the data channel with the server. Upon obtaining the push notification on the data channel during the audio portion on the phone channel, the application may correspondingly activate on the phone to participate in the non-audio portion of the communication session during the phone's participation in the audio portion (e.g., merging the portions).
