摘要： In various embodiments, icons, specific to a type of memory card (e.g., a flash memory card) inserted into a card reader may be displayed. In some embodiments, the card reader may be electrically connected to the host controller each time a memory card is inserted into the card reader. In various embodiments, different device identifications may be reported as if the card reader were actually several different card readers each dedicated to a different memory card type. A registry of an operating system may be preloaded with a different icon for each of the different card reader types. An icon may be displayed on a display specific to the type of memory card inserted. When the memory card is removed, the card reader may be electrically disconnected and the displayed icon may be removed or replaced.

摘要： A method of providing simultaneous voice and data communication for multiple ports in a digital line card of a PBX is provided. In one form, 64 K baud non-blocking voice communication for seven coupled ports and simultaneous 9.6 K baud user data communication for each port may be implemented in a single conventional line card. Voice and data bits are transmitted in frames comprising thirty-two time slots. Data bits from the various user ports are multiplexed into a single eight bit time slot. Voice bits for each port are transmitted in eight bit time slots. In one form, each time frame comprises four time slots for data and twenty-eight time slots for voice.

摘要： A multiplexed data communications modem providing high speed data communication via a single twisted pair of conductors having a distance up to two kilometers between a plurality of data terminals and remote communications equipment is provided. A burst mode ping-pong transmission scheme is utilized. A control portion selectively multiplexes data from each data terminal, and the variation of actual data rate of each data terminal has no effect on channel capacity of the other multiplexed data channels. A plurality of data interface circuits provides an asynchronous/synchronous interface between the multiplexed data terminals and a synchronous transceiver.

摘要： An energy synchronized demodulator circuit is disclosed having a differential input to single ended converter coupled to a sync detect circuit which provides a detection signal in response to the modulated input signal. The detection signal is integrated over time, and a threshold detector provides an output when the detection signal exceeds a predetermined threshold level. A filter provides a constant level output signal indicative of the presence of valid data. Synchronized demodulation is provided by a correlation between phase or frequency in predetermined bit intervals of the detection signal. Synchronization is initiated by the initial burst of input signal energy received by the differential input.

摘要： A communication system which generates an output signal of a selected primary frequency having digital data bits serially modulated thereon by utilizing a hybrid differential phase shift keyed (DPSK) modulation is provided. The improved DPSK modulation is frequency modulation of a phase encoded signal. A controller controls frequency generator means which frequency shift the output signal between primary and secondary frequencies. The controller and frequency generator means provide a modulated output signal which is D.C. balanced bit by bit and has substantially reduced harmonic energy.

摘要： A USB communications interface (USBCI) may enable communication between a high-speed USB device, e.g. a High-Speed-Inter-Chip (HSIC) USB device, and a non high-speed USB host, e.g. a full-speed USB host. The USBCI may receive first data from the USB host via a non high-speed transaction, and buffer the first data. The USBCI may also initiate a high-speed transaction corresponding to the non high-speed transaction to the USB device, and transmit at least a portion of the buffered first data to the USB device via the high-speed transaction. The USBCI may subsequently receive second data from the USB device via the high-speed transaction, and buffer the second data. The USBCI may also transmit at least a portion of the buffered second data to the USB host via the non high-speed transaction, and complete the non high-speed transaction upon the high-speed transaction completing.

摘要： In various embodiments, devices coupled to upstream ports may enumerate the USB switching hub according to the total number of downstream ports on the USB switching hub. In some embodiments, when a first upstream port is communicating with a first downstream port, status registers coupled to the second upstream port may indicate to the second upstream device that the first downstream port is disconnected. By enumerating the USB switching hub according to the total number of downstream ports, the upstream devices may not have to re-enumerate the hub (and correspondingly each device coupled to the hub) each time a downstream device is switched. In some embodiments, an intelligent port routing switch may delay switching communications for the downstream port if there is an active transfer in progress between a related downstream port and an upstream port.
摘要翻译：在各种实施例中，耦合到上游端口的设备可以根据USB交换集线器上的下游端口的总数来枚举USB交换集线器。在一些实施例中，当第一上游端口与第一下游端口通信时，耦合到第二上行端口的状态寄存器可以向第二上游设备指示第一下游端口被断开。通过根据下游端口的总数枚举USB交换集线器，每次下游设备切换时，上游设备可能不必重新枚举集线器（以及相应的每个设备耦合到集线器）。在一些实施例中，如果相关下游端口和上游端口之间存在正在进行的主动传输，则智能端口路由交换机可以延迟下游端口的交换通信。

摘要： A portable RAM drive comprising data stored on a non-volatile memory and transferable to a volatile memory when the portable RAM drive is coupled to a computer system. When the portable RAM drive is plugged into the computer system, the data from the non-volatile memory may be transferred to the volatile memory for faster access by the computer. If the portable RAM drive is unplugged from the computer, an internal power source may power the portable RAM drive long enough to transfer the data from the volatile memory to the non-volatile memory. In one embodiment, the portable RAM drive may use a restraining device or an indicator light to indicate to the user that the portable RAM drive should not be unplugged from the computer because the data has not yet been transferred from the volatile memory to the non-volatile memory.
