A method of buffering a data stream in an electronic device using a first-in first-out (FIFO) buffer system wherein the first read latch signal does not change the pointer location of the read pointer. A dynamic random access memory (DRAM) and system are also disclosed in accordance with the invention to include a FIFO buffer system to buffer memory addresses and commands within the DRAM until corresponding data is available.

There is provided a system and method for operating an electronic parcel compartment system, whereby at least one user is authorized to deposit a shipment so that the shipment can be forwarded to a logistics service provider. An exemplary method comprises acquiring data about an intended shipment and user data by a first acquisition device separated from the electronic parcel compartment system. The exemplary method also comprises supplementing the shipment information pertaining to the shipment via a second acquisition device located at the electronic parcel compartment system. The exemplary method additionally comprises verifying access rights of the user with a verification device that is arranged within the electronic parcel compartment system, by associating the acquired user data with a stored user profile and verifying validity of the acquired shipment.

A method and system for generating a reference voltage for memory device signal receivers operates in either a calibration mode or a normal operating mode. In the calibration mode, the magnitude of the reference voltage is incrementally varied, and a digital signal pattern is coupled to the receiver at each reference voltage. An output of the receiver is analyzed to determine if the receiver can accurately pass the signal pattern at each reference voltage level. A range of reference voltages that allow the receiver to accurately pass the signal pattern is recorded, and a final reference voltage is calculated at the approximate midpoint of the range. This final reference voltage is applied to the receiver during normal operation.

A logic circuit operates write receivers in a dynamic random access memory device in either a low-power mode, high write latency mode or a high-power mode, low write latency mode. The logic circuit receives a first signal indicative of whether the high-power, low write latency mode has been enabled, a second signal indicative of whether a row of memory cells in the memory device is active, a third signal indicative of whether the memory device is being operated in a power down mode, and a fourth signal indicative of whether read transmitters in the memory device are active. The logic circuit maintains power to the write receivers whenever the high-power, low write latency mode has been enabled if a row of memory cells in the memory device is active, the memory device is not being operated in the power down mode, and the read transmitters in the memory device are not active.

System and method for using a graphical user interface (GUI) to generate a measurement task specification (MTS) for performing a measurement task. The measurement task includes measurement and/or signal generation. A measurement task specifier presents a GUI which guides a user in specifying the measurement task. The GUI presents a plurality of GUI elements, e.g., panels, for specifying a plurality of parameters for the measurement task, including measurement type, devices, channels, timing, and/or triggering. The GUI receives user input indicating values for the parameters, and may provide default values for at least some of the parameters. The GUI stores the parameter values in a memory, analyzes the parameter values, and generates the MTS in response to the analyzing. The MTS is then useable to produce a program which implements the measurement task. The specifier may programmatically generate the program, e.g., a graphical program, which is executable to perform the task.

A memory device is operable in either a high mode or a low speed mode. In either mode, 32 bits of data from each of two memory arrays are prefetched into respective sets of 32 flip-flops. In the high-speed mode, the prefetched data bits are transferred in parallel to 4 parallel-to-serial converters, which transform the parallel data bits to a burst of 8 serial data bits and apply the burst to a respective one of 4 data bus terminals. In the low speed mode, two sets of prefetched data bits are transferred in parallel to 8 parallel-to-serial converters, which transform the parallel data bits to a burst of 8 serial data bits and apply the burst to a respective one of 8 data bus terminals.

Apparatus, methods and articles of manufacture are disclosed for installing an artificial eye in a realistic, life-like sculpture, comprising an artificial eye of partially hemispherical shape, as well as a manikin with an eye-mounting area adapted to mate with such an artificial eye without risk of subsequent movement of the eye or of distortion of the features surrounding the eye-mounting area of the sculpture. Eye mounting pieces for retrofitting existing sculptures having conventional eye mounting areas to permit the accurate and life-like mounting of artificial eyes are also provided.

A first-phase clock signal is generated in response to a first input clock signal. A second-phase clock signal is generated one clock cycle of the first input clock signal after generating the first-phase clock signal in response to the first input clock signal. A third-phase clock signal is generated one and one half clock cycles of the first input clock signal after generating the second-phase clock signal in response to a second input clock signal. A fourth-phase clock signal is generated one clock cycle of the first input clock signal after generating the third-phase clock signal in response to the second input clock signal.
