Abstract: Signal data obtained from a piezoelectric sensor placed on a patient's body is used to detect the presence of a cardiac pulse. The piezoelectric sensor has a transducing element adapted to sense movement due to a cardiac pulse and produce piezoelectric signal data in response thereto. Processing circuitry analyzes the piezoelectric signal data for a feature indicative of a cardiac pulse and determines whether a cardiac pulse is present in the patient based on the feature. In one aspect, the feature may be a temporal feature such as a relative change in energy. In another aspect, the feature may be a spectral feature such as the energy or frequency of a peak in the energy spectrum of the signal. In yet another aspect, the feature may be obtained by comparing the piezoelectric signal data with a previously-identified pattern known to predict the presence of a cardiac pulse. Multiple features may also be obtained from the piezoelectric signal data and classified to determine the presence of a cardiac pulse.

Abstract: A method and system are disclosed for distributed dynamic security of a document. Portions of a document are associated with a plurality of member definitions.

Abstract: A device, such as a printer or copier, identifies the type of module being used. If the type of module requires the device to receive an unlock code, the device prompts for the unlock code (which can be a hash of the serial number of the device). Once the unlock code is received, the device can be used with modules of that type. If the unlock code is not received, the device does not operate with modules of that type.

Abstract: Disclosed is a seat for use around the bathtub area. Specifically, the seat is formed so that it can fit around a side wall of a bathtub. Because there are many standard sizes of bathtubs, some embodiments of the invention include an adjustment mechanism so that the seat can be adjusted to securely attach to the side wall of most sizes of bathtubs. Other embodiments of the invention provide for a seat that can be used within the bathtub itself. Further embodiments are implemented that can sit securely on a bathtub on which a door rail is also attached.

Abstract: A pneumatic assembly for a paintball gun preferably includes a bolt slidable between an open and a closed position. The bolt preferably operates as a firing valve by permitting compressed gas to flow through the bolt when the bolt is in the closed position but preventing the transfer of compressed gas through the bolt when in the open position. This can be accomplished, for instance, by arranging a sealing member in communication with a surface of the bolt. A port is also arranged through a lateral sidewall of the bolt at a predetermined location. The bolt preferably slides in relation to the sealing member such that when the bolt is in an open position, the sealing member prevents compressed gas from flowing into the bolt, but when the bolt is in a closed position, compressed gas is permitted to flow into the bolt. Movement of the bolt is preferably controlled using a control valve such as an electronic solenoid valve.

Abstract: A paintball gun preferably includes a compressed gas storage chamber, a bolt, and a firing valve all arranged in a longitudinal chamber of the paintball gun. The bolt preferably includes a first and a second surface area. One of the two bolt surface areas is preferably larger than the other bolt surface area. The bolt can be operated by supplying compressed gas of the a selected pressure to one bolt surface area and selectively supplying compressed gas of the selected pressure to the larger of the two bolt surface areas. A firing valve can also be operated by supplying compressed gas of the selected pressure to differentially-sized surface areas of the firing valve.

Abstract: A Phase Locked Loop (PLL) that has a substantially constant gain over a wide frequency range. The frequency range over which the PLL operates is divided into a number of frequency sub-ranges. The circuit includes a mechanism for adjusting the loop gain profile as the PLL moves from one frequency sub-range to another. When the PLL switches to a new frequency sub-range, the loop gain profile is adjusted to a pre-established value. Changes of frequency within each sub-range are then accomplished with the loop gain varying within a pre-established range.

Abstract: A pneumatically operated projectile launching device preferably comprises an electro-pneumatic flow distribution mechanism that receives and directs compressed gas to a pneumatic mechanism to open a bolt.

Abstract: An apparatus for measuring data transmission performance through a packet switched network, the apparatus having a time of day (TOD) clock for determining a send TOD timestamp, and for determining a present TOD when a data packet returns to the sending apparatus. The apparatus further comprising a counter that is incremented by a send sequence number each time data is sent, and one or more subtractors for calculating a first time difference between the send TOD timestamp and a receive TOD timestamp, and for calculating a second time difference between the receive TOD and the present TOD. Additionally, one or more comparators of the apparatus compare a sequence difference between the send sequence number and a receive sequence number in order to measure data transmission performance.

Abstract: ATA devices, such as mass storage units, have increasingly larger storage sizes that use larger configuration register sizes. A command block format allows the USB/ATA bridge circuit to be used with ATA devices with larger registers and at the same time operates with earlier ATA command block formats.

Abstract: A pneumatic assembly for a paintball gun preferably includes a bolt slidable between an open and a closed position. The bolt preferably provides a firing mechanism for the paintball gun by permitting compressed gas to flow through the bolt to fire the paintball gun when the bolt is closed but preventing the transfer of compressed gas through the bolt when the bolt is open. This can be accomplished, for instance, by arranging a sealing member in communication with a surface of the bolt. A port is also preferably arranged through a lateral sidewall of the bolt at a predetermined location. The bolt preferably slides in relation to the sealing member such that when the bolt is open, the sealing member prevents compressed gas from flowing into the bolt, but when the bolt is closed, compressed gas is permitted to flow into the bolt. The bolt is preferably controlled by using a control valve such as an electronic solenoid valve to operate a pneumatic piston.

Abstract: An integrated hydraulic control system includes a steering control unit and a priority flow divider integrated into a unitary casing. An interface fluidly couples the casing for the steering control unit and priority flow divider directly to a control valve casing. All hydraulic communication between the steering control unit, the priority flow divider, and the control valve are located inside the casings.

Abstract: A network device to maintain resource management within a network may comprise an emulator or watchdog that may send an emulation request to a resource manager for emulating a request of a client. Operability of the resource manager may be identified based on a reply of the resource manager to the emulation request. If the resource manager does not provide a response within a given time frame, then the watchdog may identify a failure condition for the resource manager. The watchdog may then initiate corrective actions for replacing the resource manager with a backup server responsive to identifying the fail condition.
