Abstract:
In a communication system capable of variable rate transmission, scheduling of high speed data transmission improves utilization of the forward link and decreases the transmission delay in data communication. Each remote station is assigned one primary code channel for the duration of the communication with a cell. Secondary code channels of various types and transmission capabilities can be assigned by a channel scheduler for scheduled transmission of data traffic at high rates. Secondary code channels are assigned in accordance with a set of system goals, a list of parameters, and collected information on the status of the communication network. Secondary code channels can be grouped into sets of secondary code channels. Data is partitioned in data frames and transmitted over the primary and secondary code channels which have been assigned to the scheduled user.

Abstract:
A peripheral device connection current compensation circuit is proposed, which is designed for use in conjunction with a peripheral control interface on a computer platform, for the purpose of responding to an event of an external peripheral device being connected to the peripheral control interface by providing a current compensating function that can help to prevent an electrical current induced by a pull-up resistor in the peripheral device from flowing into the internal circuitry of the peripheral device. This feature can help maintain the slew rate of the connecting circuitry for the peripheral device at the rated value.

Abstract:
Novel techniques are disclosed for detecting discontinuous transmission (DTX) over a communication channel. A received data frame is characterized as one of a Good frame, Erasure, or DTX. If a Good frame is not initially detected, a multi-dimensional quality metric is used to characterize the received frame as either an Erasure or DTX. A two dimensional quality metric may be generated using energy per bit to noise power ratio as a first dimension and re-encoded symbol error count as a second dimension. Alternatively, re-encoded symbol energy may be used as the second dimension of the quality metric. The communication channel may be a CDMA wireless communication channel capable of DTX and the device may be a base station, base station controller, or mobile station.
Abstract:
Access to a variable rate multiple access system is controlled based upon a current loading. The current loading level is used to determine a transmission rate set point. The transmission rate set point may include a maximum transmission rate and a transmission probability. The transmission rate set point is passed to the remote unit which may access the system. A remote unit with data to send determines a desired transmission data rate. If the desire transmission data rate is equal to or greater than the maximum transmission data rate, the remote unit transmits at the maximum transmission data rate with a probability equal to the transmission probability.
Abstract:
A handy type smoke generator includes a housing, a container, a drawing device, a transfer tube, a heat-resisting tube and a heating vaporizing device. The smoke generator is characterized in that a drawing device is provided between the container and the transfer tube, and includes a hollow tube fitted with a fastening ring member, and a core rod with an elastic ring connected thereto below. The core rod is provided with a through rod hole. A sealing cap abuts against the fastening ring member. A hollow pump is coupled with the fastening ring member such that the sealing cap is sandwiched therebetween. The elastic ring abuts against the inner wall of the pump. The pump has a retractable spring disposed therein and between the core rod and the bottom portion of the pump, and a plug ball removably closes a pump hole in the bottom portion of the pump. The bottom portion of the pump is further provided with an extension tube for extension into the bottom portion of the container. The tube has a top portion fitted with a press member which is formed with a liquid outlet in a lateral side thereof for connection with the transfer tube. The sealing cap is used to connect with the coupling portion at the top portion of the container. By pressing and releasing the press member several times, the solution within the container is pumped into the transfer tube by pumping action of the pump and flows through the heat-resisting tube into the heating vaporizing device. The solution is vaporized to form smoke that is ejected via a nozzle.
Abstract:
A method for evaluating ratios of metallic impurities in lithographic materials is disclosed. The method comprises: separating said metal from said lithographic material by microwave heating; then adding said metal to an acid to form a solution; and finally analyzing said solution by a instrument to measure ratio of said metal.
Abstract:
A new structure for a printed circuit board slot connector for securing the inserted printed circuit board and provides electrical contacts between the inserted printed circuit board and the mother board. Said connector mainly comprises a plurality of electrical conducting plates which are grouped together in a band. Said band of conducting plates can be installed into the connector from the bottom of the shell body in a single operation. Mechanical operation is used to cut and isolate the conducting plates from one another. The internal contact pins are longer than the external contact pins. Below the point of contact of the conducting plate with the printed circuit board is a projected portion which strengthens the conducting plate. In addition, either one of the three types of securing members is designed in the structure of the connector: at least one printed circuit board securing member is designed in an appropriate location of the internal shell body, said printed circuit board securing member is used to secure the mounting of the printed circuit board, or at least one mother board securing member is installed such that the connector can be securely mounted on the mother board, or at least a dual-usage securing member is installed as the printed circuit board securing member or the mother board securing member.
