  • Publication number: 20120156081
    Abstract: An improved structure of a central shaft in a pneumatic actuator comprises an actuator having an actuator chamber; a vane which is hingedly located at a shaft hole of the actuator. The central shaft is cylindrical and short, and the short central shaft has a through hole which is a through octagonal opening symmetric to a center thereof. It can be easily processed and precisely aligned. The advantage of the short central shaft is that the actuator itself can connect to non-pressured sources such as an upper and lower central shafts, and connect to different inserting drivers to form a central shaft as a unit in the pneumatic actuator to directly connect to a central shaft of a valve or indirectly through a connecting bracket instead of using a conventional connecting coupler. The octagonal opening provides alignment positions at every 45 degrees for the upper and lower central shafts to increase diversities of usage.

  • Publication number: 20120041907
    Abstract: To suggest new connections to a user of a social networking system, the system generates a set of candidate users to whom the user has not already formed a connection. The system determines the likelihood that the user will connect to each candidate user if suggested to do so, and it also computes the value to the social networking system if the user does connect to the candidate user. Then, the system computes an expected value score for each candidate user based on the corresponding likelihood and the value. The candidate users are ranked and the suggestions are provided to the user based on the candidate users' expected value scores. The social networking system can suggest other actions to a user in addition to forming a new connection with other users.

  • Publication number: 20110248834
    Abstract: This invention provides a method and system for inventorying wireless transponders, specifically referred to as RFID transceiver devices. The RFID transceiver devices are certifiable by a recognized standards body, such as EPCglobal, or are compatible with recognized standards but have higher functionality than typical passive RFIDs, and yet are implemented with techniques that lower cost and battery requirements. Backscatter techniques of standard passive RFIDs are used to keep cost and battery requirements low. To provide higher functionality, a microcontroller is used in the RFID, along with a battery, but the clock frequency of the microcontroller is adjusted, based on external input, to minimize battery requirements. In one embodiment, the microcontroller initially has a zero or near zero clock frequency.

  • Publication number: 20110176464
    Abstract: The present invention provides a method and system for establishing a highly mobile, long range secure wireless network with dynamic topologies and near full connectivity with acceptable latency using low cost, low power, compact and lightweight devices. One aspect of the system deals with a highly mobile network with dynamic network topologies and a time varying wireless medium that has neither absolute nor readily observable boundaries outside of which radio nodes are known to be unable to receive network frames, although the desirable open field boundary is 1 mile in radius from a base station node. A synchronous frequency hopping technique is used with mobile nodes that can become slave base station nodes to a master base station node to increase the effective range of the master base station without increasing the transmit power.

  • Publication number: 20110169745
    Abstract: A 5-wire touch screen system includes a touch screen (10) including a wiper (11) and a resistive layer (16) aligned with the wiper and first (UL), second (UR), third (LR), and fourth (LL) resistive layer contacts, wherein a touch on the screen presses a small portion of the wiper against the resistive layer, producing a touch resistance (RZ) between them at a touch point on the resistive layer. The wiper and various contacts are selectively coupled to first (VDD) and second (GND) reference voltages, respectively, to generate an analog touch voltage (VZ) at the touch point. The wiper and various contacts are selectively coupled to an analog input (56) and a reference voltage input of an ADC (48) for converting the touch voltage (VZ) to a digital representation. Analog voltages (VX) and (VY) at the touch point are converted to corresponding digital representations by the ADC.

  • Publication number: 20110092793
    Abstract: Treatment targets such as tumors or lesions, located within an anatomical region that undergoes motion (which may be periodic with cycle P), are dynamically tracked. A 4D mathematical model is established for the non-rigid motion and deformation of the anatomical region, from a set of CT or other 3D images. The 4D mathematical model relates the 3D locations of part(s) of the anatomical region with the targets being tracked, as a function of the position in time within P. Using fiducial-less non-rigid image registration between pre-operative DRRs and intra-operative x-ray images, the absolute position of the target and/or other part(s) of the anatomical region is determined. The cycle P is determined using motion sensors such as surface markers. The radiation beams are delivered using: 1) the results of non-rigid image registration; 2) the 4D model; and 3) the position in time within P.
