Abstract: An ultra-low power wakeup circuit device includes a keyboard, a key scan circuit, a storage unit, and a comparator unit. The key scan circuit sequentially outputs scanning signals from the first scan line to N-th scan line for acquiring N key scan data. The key scan circuit performs an XOR operation on the N key scan data to generate a current key scan data. The storage unit is connected to the key scan circuit for receiving the current key scan data and storing the current key scan data as a previous key scan data. The comparator unit is connected to the key scan circuit and the storage unit for comparing the current key scan data with the previous key scan data. When the current key scan data is different from the previous key scan data, the comparator unit generates a wakeup signal.

Abstract: An internet based social networking system, the system including: a number of video sensors monitoring a specified environment and streaming video into the system; a series of system users collectively monitoring the video streams and analyzing events generated in relation to the video stream; and a reporting system for reporting actions taken by the system users among the system users.

Abstract: An information synchronization method includes acquiring declaration information of a first local area network device that is in a first local area network. The declaration information includes a private address of the first local area network device in the first local area network. The private address of the first local area network device is mapped into a corresponding external address according to a preset mapping relation between private addresses and external addresses. A notification message carrying the external address of the first local area network device is sent to a second local area network, so as to enable the second local area network to store the external address of the first local area network device and notify a state of the first local area network device to a second local area network device in the second local area network.

Abstract: A system and method are disclosed for enhancing the throughput of signals from a security system receiver to an associated automation server. Multiple parallel Ethernet connections or ports are provided between the receiver and server to enable multiple signals to be transmitted between the two when such signals are received from a client's security system panel. The system and method may access the ports in a variety of orders to provide efficient transmittal of signals from the receiver to the server. In one embodiment, received event signals may be routed though the ports in numeric sequence, forward or reverse. In another embodiment, received event signals may be routed preferentially to the first port, if it is not busy. If the first port is busy then the signal may be routed to the second port, and so on. In a further embodiment, received event signals from specific client panels may be directed through predetermined ports, and a predetermined automation server at the central monitoring facility.

Abstract: Methods, systems, and apparatus, including computer program products, for managing resources in virtualization systems, including multi-cloud systems. The use of supply chain economics alone and in combination with other techniques offers a unified platform to integrate, optimize or improve, and automate resource management in a virtualization system. These techniques may be used to monitor and control the delivery of service level agreements and software licenses. They may also be used to monitor and control contention of computing resources in a virtualization system, and to suspend or terminate computing resources.

Abstract: A method is presented for transmitting data in a satellite system having multiple spot beams comprising (1) sending a broadband signal in a forward direction from a gateway terminal to a communications satellite for relay to at least one subscriber terminal, (2) receiving the broadband signal at the communications satellite, wherein the communications satellite comprises a bent pipe repeater having a plurality of satellite-based transmission amplifiers, (3) using one of the plurality of satellite-based transmission amplifiers to amplify the broadband signal and no other broadband signal from the gateway terminal, to produce an amplified broadband signal, (4) sending the amplified broadband signal as one of a plurality of service spot beams to the at least one subscriber terminal, and (5) receiving and retrieving data from the amplified broadband signal at the at least one subscriber terminal.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for preventing server overload. In one aspect, a method includes placing each request of a plurality of requests into a queue. Requests are popped from the queue, and for each popped request, in response to popping the request: a counter value is incremented; computing resources are allocated for the request; a determination is made that a condition for which computing resources allocated for the request can be de-allocated has occurred; and the counter value is decremented after the condition occurs. In response to determining that the counter value does not exceed a threshold number, requests continue to be popped from the queue. In response to determining that the counter value exceeds the threshold number, requests are not popped from the queue until the counter value is decremented to or below the threshold number.

Abstract: An integrated circuit with a rectifier element. One embodiment provides a signal source, an electronic circuit and a rectifier element with a copper layer and a cuprous oxide layer adjacent to and in direct contact with the copper layer. The signal source is configured to drive a signal on a signal output terminal that is electrically coupled to the copper layer. The electronic circuit is electrically coupled to the cuprous oxide layer. The rectifier element may be formed between wiring layers of an integrated circuit.

Abstract: A wireless apparatus having a non-electric power-type wake-up function that operates a wake-up circuit waking-up a microprocessor for communications without power. There is provided a wireless apparatus having a wake-up function, including: a wake-up unit that has a rectifying circuit having elements configured as passive elements and rectifies preset first wireless signals to transmit wake-up signals; and a wireless communications unit that is woken-up by the wake-up signals from the wake-up unit to perform communications using preset second wireless signals, in a sleep mode.

Abstract: An electrical power diagnostic system includes a system housing, a power saw management system, and a user interface. The system housing is electrically connected with the power unit of the power saw, wherein the system housing includes a control panel provided thereon for allowing a user to adjust an operational parameter through the control panel. The power saw management system includes a control processor mounted within the system housing to electrically communicate with the power saw, wherein the control processor is pre-programmed to manage operational parameters of the power saw and supervise actual operation of the power saw machine and the saw blade in such a manner that when abnormal operating condition of the power saw machine is detected, the control processor is adapted to selectively adjust the operational parameters of the power saw machine for stopping the abnormal operating condition from continuously happening.

Abstract: A single fibre channel switch or serial attached SCSI expander applies zoning on the initiator ports to each of the two ports of one or more drives. The fibre channel switch or serial attached SCSI expander uses zoning to connect both ports of each drive to a single expander and set the zones in the expander such that each zone includes at least one initiator port and one drive port.
