A circuit that performs a prefix computation. This circuit includes an N-bit prefix network of prefix cells arranged into L+l logic levels, wherein the prefix network computes N outputs {YN, . . . , Y1} from N inputs {XN, . . . , X1} using an associative two-input operator ∘, such that, Y1=X1, Y2=X2∘X1, Y3=X3∘X2∘X1, . . . , and YN=XN∘XN−1∘ . . . ∘X2∘X1. Within this prefix network, each prefix cell has a fanout of at most 2f+1, and there are at most 2t horizontal wiring tracks between each logic level. Additionally, l+f+t=L−1, and unlike existing prefix circuits, 1>0,f>0, and t>0.

摘要:
One embodiment of the present invention provides a system that achieves low gate leakage current in an integrated circuit during sleep mode. Upon entering sleep mode, the system reduces the power supply voltage applied to the integrated circuit to a low voltage level, wherein the low voltage level is low enough to provide a low gate leakage current, but is high enough to maintain state in the integrated circuit.

A heat sink for a magnetically tuned filter provides an insulative gap between the magnetic coils and the magnetic housing and pole pieces and has a thermally conductive plate in thermal contact with the magnetic coils with a flange portion extending exterior of the magnetic housing so that heat generated by the magnetic coils is conducted for dissipation external of the magnetic housing. The thermally conductive plate has a central opening in which a filter housing is situated, has a plurality of channels between the central opening and the outer edge to provide for electrical and mechanical access to the filter housing, and has a radial insulative gap from the central opening to the outer edge to prevent the formation of eddy currents in the thermally conductive plate.

Foundry apparatus for mixing sand with binder ingredients to produce a composite mixture suitable for foundry molds includes a first premixing chamber enclosing a first bladed shaft mounted for rotation about a substantially horizontal first axis operable for conveying and commingling sand with a first binder ingredient to produce a first sand/binder ingredient mixture. A second premixing chamber, separate from the first premixing chamber, encloses a second bladed shaft mounted for counterrotation about a second axis, substantially parallel to the first axis, for conveying and commingling sand with a second binder ingredient to produce a second sand/binder ingredient mixture. A final mixing chamber includes agitators for receiving the sand/binder ingredient mixtures and blending them into a composite mixture while simultaneously transporting the composite mixture to a final discharge station. A single power-driven unit operates for driving the first and second bladed shafts, which in turn, operate the first and second agitators.
摘要:
A mobile station receives a neighbor list from a base station in an area of a public wireless network that borders a private wireless network. The neighbor list includes encrypted channel identifiers corresponding to private network channels transmitted by the private wireless network and unencrypted channel identifiers corresponding to public network channels transmitted by the public wireless network. If the mobile station does not subscribe to the private wireless network, the mobile station does not recognize the encrypted channel identifiers and simply ignores them. However, if the mobile station subscribes to the private wireless network, the mobile station decrypts the encrypted channel identifiers and determines whether it is able to initiate a handoff to any of the corresponding private network channels.

A method of operating a communication system is disclosed. A time sensitive data stream is sent to a wireless device via a first wireless station. A handoff criteria is determined to have been satisfied. Based on the handoff criteria being satisfied, at least one control message is sent that instructs the wireless device to increase a buffer size associated with the time sensitive data stream.

One embodiment of the present invention provides a system that uses electrostatic forces to align semiconductor chips relative to each other. The system operates by fabricating a first set of conductors on the top surface of a first chip and fabricating a corresponding second set of conductors on the top surface of a second chip. To align the chips, the system electrically charges the first set of conductors and the second set of conductors. The system also places the first chip face-to-face with the second chip, so that the first set of conductors is in close proximity to the second set of conductors. This allows electrostatic forces between the first set of conductors and the second set of conductors to bring the first chip into alignment with the second chip and to hold them in place.
摘要:
A control circuit for a FIFO datapath is described. The control circuit consists of a chain of Muller C-elements with adjustable delay elements placed between the output of each Muller C-element and one of the inputs of the preceding and successive Muller C-elements. The adjustable delay elements allow the control circuit to match the delays of processing elements in the datapath, thereby creating overall faster operation.

A bird feeder comprising a main body having an open top end and an open bottom end, a lid selectively removably affixed to the top end of the main body, a base affixed to the bottom end of the main body, and one or more hanging bird food receptacles suspended from the lid and selectively removable from the main body when the lid is selectively removed from the top end of the main body. The main body, the lid, and the base together form an enclosure when the lid is selectively affixed to the top end of the main body.
