Abstract:
A case for holding an audio device having a female audio jack. The case has a removable cover including a male audio jack for electronically connecting the cover to the female audio jack of the audio device. The cartridge includes a spool and houses an ear bud cable. The ear bud cable has a first end with at least one ear bud, and a second end attached to the spool. The cartridge has a rotatable spool for selectively retracting and dispensing the ear bud cable. The spool electronically connects with the male audio jack to enable audio communication between the audio device and the ear bud. In one embodiment, the spool electronically connects with the male audio jack via a jumper wire. In another embodiment, the spool electronically connects with the male audio jack via an electrical contact pad integrated into the case.
Abstract:
A cartridge usable with a portable electronic device for managing an ear bud cable comprises a housing having a hub, a spool and stationary audio contacts fixed with respect to a hub axis. The stationary audio contacts are annular in shape and insulated from each other and from the housing. The stationary audio contacts are spaced equally from each other, and are each placed at fixed distance from the hub axis. The annular stationary audio contacts connect electrically with an auxiliary audio jack and a contact pad for simultaneously connecting the device to more than one audio device. Conductive contacts are placed on a bottom side of the spool, and are spring loaded to maintain continuous electrical contact with the stationary audio contacts.
Abstract:
A low cost, sealed contactor comprises a hermetically sealed housing with a flat header having internal components for changing the state of said contactor. Terminals are electrically connected to the internal components for connection to internal circuitry and applying an electrical signal to control the state of the contactor. A solenoid-driven plunger with a hollow shaft is included. Power-reducing electronics located within the hermetically sealed housing are also included. Two contact springs are also included to improve electrical performance. O-rings are added to help seal the contactor and keep it hermetically sealed.
Abstract:
A communication console station links a plurality of communication resources (101, 103, and 105) for use by an operator. Incoming calls are placed in an incoming-call queue (207), calls on hold are placed in a holding queue (209), and all available communication resources are placed in a resource queue (211) The operator presses a single button (303, 305, or 307) to obtain the top resource from the associated queue (207, 209, or 211), which lists resources according to a predetermined priority.
Abstract:
A cryostat cooling system cools the central processor (CP) circuit boards of a computer to enhance the performance of the electronic components of the central processor. The cryostat includes a pair of concentrically positioned circular cylindrical shells. The inner shell is suspended from the outer shell by a thin (small cross-section) thermal isolation support ring. A vacuum chamber is formed between the inner and the outer shells. The top of the inner shell is covered by an inner shell top plate having a pair of openings through which the CP boards are inserted. A pair of containment vessels are mounted below the inner shell top plate to receive the CP boards. An inlet supply tube is connected to the containment vessel to supply liquid nitrogen. Overflow vents permit excess liquid nitrogen and nitrogen gas to flow from the containment vessels into the interior of the inner shell. A drain tube is connected to the inner shell to remove and recirculate the gaseous and liquid nitrogen from the interior of the inner shell. Each CP board is connected to an associated central processor memory board by a connector block which seals the opening while permitting the flow of signals between the central processor memory and the central processor.
