Abstract: The invention is a method and apparatus for compression of binary data. The signal is used before modulation to increase the effective transmission rate by compressing it prior to being encoded onto a magnetic tape or other storage media. The transition bits of the data have a bit period no smaller than the smallest bit period without increasing the maximum frequency. However, non-transition bits have a bit period smaller than that of the transitioning bits. Since there is at least one full bit period between any two transitions, the maximum frequency is unaffected and is used for synchronization. Noise in a transmission is masked using bit period information, and since no other transition can be valid until at least the transition bit period has passed, noise occurring before passage of the transition bit period does not result in an error.

Abstract: A resealed inkjet printer cartridge and method of manufacture in which an ink cartridge is reconditioned, recharged and resealed by a centrifugation process which substantially eliminates “air lock” or interruption of ink flow to the printer head due to entrained air; which provides for welding together recharged cartridge subassemblies without the use of consumable adhesive or glue; and having a keyless cap adapted for use in various keyed cartridge receptacle inkjet printers.

Abstract: A differential capacitive torque sensor for a continuously rotating shaft such as the steering column of an automobile provides an apertured metal cage shielding a dielectric rotor. They are respectively mounted on opposite sides of a split shaft connected by a torsion bar. The relative rotation of the apertured conductive plates and the rotor change the overall differential capacitance of the system to proportionally indicate clockwise or counter-clockwise torque.

Abstract: A method and a device is provided for increasing the shelf life of an oxygen sensitive product such as ground meat by injecting an inert gas or blend of inert gases into the ground meat through a stopper as meat is being pushed toward the stuffer outlet and a conveyor to a chub packager. By introducing the inert gas at this early stage in the chub packaging operation, the oxygen content within each chub is reduced to 0.5% and less using the present invention. The inert gas forces substantially all of the ambient air away from the entire surface area of the ground meat as it is being circulated in the lower portion of the stuffer hopper and prior to being forced out through the stuffer outlet.

Abstract: The invention relates to a buffer memory, method and a buffer controller for queue management usable in an ATM switch. An object of the invention is to achieve a high frequency throughput of data cells in the buffer memory. This object is achieved by using a buffer memory which is organized as 256*(424+8) SRAM-cells. The memory is used for holding ten queues, one for each incoming channel and two free-queues containing idle cells.

Abstract: The description relates to securely and autonomously synchronizing data on geographically distributed computers. Data is distributed from a central server to geographically distributed clients. In another embodiment, data is encrypted and securely transmitted over a computer network. It uses the Secure Sockets Layer protocol to secure transmitted data. The data is transmitted via the Internet. Data is distributed in real-time. Data is provided to a user as the data updates without the user making a specific request for updated data. Portions of data are made available to only authorized users. An administrator sets permissions to control which data is transmitted to a user. The transmission of data is secure in both directions. Data transmitted to a user from a central location is secure and data transmitted to a central location from a user is secure. Data is securely transmitted to a user independent of the platform on the user's machine.

Abstract: Embodiments of the present invention are directed to a method and apparatus for heat pipe cooling of an excimer lamp. In one embodiment, a heat pipe is used to dissipate heat from an excimer lamp. The heat pipe is in direct contact with at least one electrode of the excimer lamp. In one embodiment, heat is transferred through the heat pipe to a cooling point that is electrically isolated from the lamp. In one embodiment, dissipation of heat from the cooling point is done by conventional means. In one embodiment, the heat pipe is on the inside of the lamp. In another embodiment, a heat pipe is attached to the outside of an excimer lamp. In another embodiment, two heat pipes are used, one on the inside and one on the outside of an excimer lamp. In yet another embodiment, a heat pipe is used with a flat lamp.

Abstract: The present invention is a class of circuits named asynchronous pulse logic (APL) circuit and designing methods for such circuits. APL replaces two of the four-phase handshakes in QDI circuits with pulses, thus breaking the timing dependencies that cause performance problems in QDI circuits. Since the pulse length in APL varies so little, it can be assumed constant. This assumption frees designers from needing to consider the effects of the inputs and outputs on the pulse length, which means timing properties can be verified locally. One embodiment of the present invention is a class of circuit design called the single-track-handshake-asynchronous-pulse-logic (STAPL), which serves as a new target for the compilation of CHP (Communication Hardware Process) programs. In one embodiment, a five-stage pulse generator is used to create a 10 transition count cycle circuit. Advantages of STAPL include a simplified solution to the charge-sharing problem and less loading from p-transistors.

Abstract: The present invention provides an arc path formed in a lamp body. In accordance with one or more embodiments of the present invention, the lamp body has a plurality of closely spaced, parallel vanes which form an arc path. In one embodiment, the lamp body comprises a bottom and top plate, and a front and back sealing member. The bottom plate may be a flat plate which can be made of quartz or other suitable material. The plate has a plurality of vanes machined into it out to its edges. Alternatively, the vanes may be separate and sealed onto the bottom plate. The top plate is sealed to the bottom plate. The front and back sealing members are sealed to the plates to complete the seal of the lamp body. In another embodiment, the bottom plate is a solid block of quartz or other suitable glass material, which can have the vane pattern machined onto it stopping short of the edges. The solid block is then sealed at the top and outside edges by the top plate, without the need for front and back sealing members.
