A system and method for a virtual omni-directional camera array, comprising a video control system (VCS) coupled to two or more co-located portable or stationary information processing systems, each enabled with a video camera and microphone, to provide a composite video view to remote videoconference participants. Audio streams are captured and selectively mixed to produce a virtual array microphone as a clue to selectively switch or combine the video streams from individual cameras. The VCS selects and controls predetermined subsets of video and audio streams from the co-located video camera and microphone-enabled computers to create a composite video view, which is then conveyed to one or more similarly-enabled remote computers over a broadband network (e.g., the Internet). Manual overrides allow participants or a videoconference operator to select predetermined video streams as the primary video view of the videoconference.

An electronic pool pump timer that controls the run time of the pump for a period of time each day depending on the date. In the preferred embodiment, the user enters the historical daily maximum and minimum pump run times for the specific pool and the system calculates the required time the pump will run on a given day. The customized run time is thus calculated as a function of the date and the minimum and maximum run times for a given pool. The system then self-adjusts the run time each day as necessary. The device comprises a data input means, a display, memory, and a controller. It may also include a manual override to allow the user to turn the pump on at any time. The device is connected to the pump motor. The device is connected to a power supply and may also include a battery back-up in the event of a power outage. To prevent the pool from freezing, the system may also include an air temperature sensor that triggers pump operation when the ambient air is below a given temperature.

A display system that communicates with existing automated meter reading communications systems to provide information to a user. The display includes a radio that listens to communications between a utility meter and the reading system. When the display recognizes a particular utility meter identifier, it captures meter read information and stores it in memory. The information may then be presented to the user. Alternatively, a broadcast message may be communicated, that when received by the display, causes the display to extract information from the receiver. A manual override button may be provided to allow a user to manually request information from the meter. The display will extract information from the meter upon receipt of the manual request.

A subsea actuator and method is disclosed that includes all moving components mounted in a compact, concentric configuration. The subsea actuator is highly reliable and will operate at depth even with zero valve body cavity pressure. A preferably cup-shaped spring pusher is provided in telescoping relationship to the hydraulic chamber. A piston position indicator is provided which is connected externally to the hydraulic piston cylinder to avoid the possibility of hydraulic leaks due to the piston indicator. A manual override may be provided with a manual override indicator. The manual override indicator has a shorter travel length than the manual override operating stem to thereby reduce the overall length of the manual override assembly. The driving stem provides a removable connection to the hydraulic piston from the top of the actuator housing and a quick disconnect permits disconnection of the driving stem from the valve stem. In a preferred embodiment, upper and lower t-slot connections are utilized in the driving stem assembly. In a preferred embodiment, two back seat valves are removably secured to the driving stem to engage respective seats and provide additional sealing around the driving stem so as to prevent leakage between the valve chamber and actuator housing chamber. The high tension spring does not need to be removed to perform maintenance, and all wear items and seals are readily accessible. Change or replacement of the stem packing is made from the top of the bonnet to avoid dissasembling the bonnet to valve body connection. Pre-load bolts are used to adjustably preload the tension in the return spring. The height/weight of the actuator is significantly reduced as compared to prior art subsea valve actuators.

Systems, apparatuses and methods are described for shuffling a deck, group, stack or pile of cards. The cards are placed into a shuffler. The shuffler may be accessed under a lid, or via a slot or tray. Buttons, switches, or a touch screen and the like serve as an interface to access and control the shuffler. Cards are introduced into a substantially vertical shuffling chute. Cards are counted or audited. Sensors provide information as to the location of the cards. Static barriers and agitators encourage cards to remain in proper orientation and location. An elevator lifts cards from the shuffling chute. Sweeper arms or other mechanism manipulates the cards and returns the cards to a substantially horizontal orientation and exit position. Manual override is possible when errors are detected. Rubber-coated commodity rollers mountable to cantilevered axles engage and launch cards into the air when shuffled in the shuffling chute. Cards settle back into the stack of cards under the influence of gravity. The shuffler is mounted inside a simple enclosure. Maintenance and interface features provide convenience when working with the shuffler. Authentication may be employed to correlate user or dealer with operation of the shuffler.

A gun lock for receiving and clamping a cross-sectional portion of a firearm. A slide bar is provided for mounting the gun lock to a surface in a storage location such as a motor vehicle, home, office, a cabinet or any surface where a gun might be stored. A locking assembly slidably mountable to the slide bar is provided. A pivotably attachable ratchet arm which resembles typical handcuffs is provided. One arm has a plurality of ratchet teeth that enables the gun lock to clamp a wide variety of cross-sectional portions of weapons having different configurations. A solenoid activatable locking assembly is positioned within the lock. The solenoid has a plunger adapted to engage one of the ratchet teeth of the ratchet arm to lock the rotatable ratchet arm in position around the cross-sectional portion of the weapon to be locked. The solenoid locking assembly is releasable via a switch. A manual override assembly is also provided. The manual override assembly is activated with a key. Once the key is turned, a camlock that is connected to the plunger of the solenoid locking assembly causes the plunger to move. When the key is turned in one direction, the arm rotates and the plunger disengages from the ratchet teeth of the ratchet arm. When the key is turned in the opposite direction, the plunger again engages one of the ratchet teeth to again lock the locking assembly. A set screw assembly for releasably locking the locking assembly onto the sliding bar is provided. A set screw and a set screw nut locks the locking assembly onto the slide bar. The set screw is accessible by a hex key through an opening in housing of the apparatus only when the ratchet arm is in the unlocked open position.
