Abstract: A network sensor system is provided that is capable of extremely low-power operation. The network sensor system implements a communication protocol that allows the sensors to operate at most times in a sleep mode, where only a low-power time is active. In this way, each sensor's receiver, transmitter, and support circuitry are operated only when strictly necessary. The network has a defined network time frame, and each device maintains and adjusts its own clock and relationship with the network time. In this way, each sensor is aware about when it may be sent a message, and opens a short listen window only when such a message is expected. If no message is received, or if the message is addressed to another sensor, the sensor goes back to sleep. The sensor's transmitter is only activated in the case where the message 1) is received during the listen period, 2) is addressed to the sensor, and 3) requires a transmission action. Otherwise, the transmitter remains deactivated.

Abstract: A distributed VoIP system includes a network and a first switch at a first site coupled to the network. The first switch is configured to provide telephony services to a first communication device. The system also includes a second switch at a second site coupled to the network. The second switch is configured to provide telephony services to a second communication device. The system also includes a spare switch coupled to the network. The spare switch is configured to provide telephony services to the first communication device if the first communication device is unable to register with the first switch, and the spare switch is configured to provide telephony services to the second communication device if the second communication device is unable to register with the second switch.

Abstract: A synthetic turf surface including a synthetic grass carpet having a flexible base sheet, and a shock absorbing pad, wherein the shock absorbing pad includes a non-crosslinked polyolefin foam is shown and described. The foam may be recyclable, as it is non-crosslinked.

Abstract: A portable electronic device having a pattern identification system includes a substrate, an illumination device, a video camera unit (containing a controllable camera lens), a controller, a programmable identification element and a display unit. The substrate is electrically connected to the illumination device, the video camera unit, the controller, the programmable identification element and the display unit. The illumination device initially projects light on a sample pattern. The controller controls the video camera to magnify an image sufficient for identification at the predetermined position of the sample pattern so as to allow capturing an identifiable image of difference with respect to a programmed feature. The video camera unit captures the identifiable image of the predetermined position of the sample pattern and sends it to the programmable identification element for identifying the sample pattern. The display unit displays an identified result of the sample pattern.

Abstract: A pattern identification system for an automatic teller machine includes an illumination device, a video camera unit, a controller and a programmable identification element. The illumination device initially projects light on a sample or security pattern. The controller controls the video camera to magnify an image sufficient for identification at the predetermined position of the sample or security pattern so as to allow capturing an identifiable image of difference with respect to a programmed feature. The video camera unit captures the identifiable image of the predetermined position of the sample or security pattern and sends it to the programmable identification element for processing identification of the sample or security pattern.

Abstract: A voiceprint identification method for transacting e-commerce includes the steps of: accessing user's login via electronic communication means; an identification device recognizing a password; the identification device verifying voiceprint registration of users whether a voiceprint of the assessed user is registered; a voiceprint identification system identifying the assessed user's login or approving registration of a voiceprint of the user; and the voiceprint identification system determining the user to approve or disapprove in transacting e-commerce.

Abstract: A pattern identification system includes a platform, a conveying device, an illumination device, a video camera unit, a controller, a programmable identification member and a switching member. The conveying device transports a feeding sample sheet on the platform mounted in the pattern identification apparatus. The illumination device projects light on the sample sheet. The controller controls the video camera to magnify an image with a predetermined multiple sufficient for identification at the predetermined position of the sample pattern so as to allow capturing an identifiable image of difference with respect to a programmed feature. The identifiable image of the selected pattern is captured and sent to the programmable identification member for identifying the selected pattern of the sample sheet. After identifying, the switching member is switched for outputting and sorting the sample sheet by the controller in response to a control signal of the programmable identification member.

Abstract: A pattern identification system includes an illumination device, a video camera unit, a controller and a programmable identification member. The illumination device projects light on a sample pattern disposed in the system. The video camera unit captures a first image for measuring a reference coordinate of the sample pattern. The video camera unit is moved to a predetermined position by the controller. The controller controls the video camera to magnify an image sufficient for identification so as to allow capturing an identifiable image of difference with respect to a programmed feature. The video camera unit captures a second identifiable image of the sample pattern and sends it to the programmable identification member for identifying the sample pattern.
