40results about How to "High data transfer" patented technology

A thermostat control system having remote devices and / or other internally powered devices provides transmissions at different power levels and at different data transfer rates to conserve power life. Thermostat control system components and devices may be powered by replaceable power supplies that are conserved by transmitting at a lower power level more often than at a higher power level. A higher power level transmission is provided at a lower data transfer rate, and a lower power level transmission is provided at a higher data transfer rate. A higher power transmission is provided periodically to ensure reliable communication of temperature information.

There is provided a technology to realize high speed data transfer while compatibility of a card type storage device comprising a nonvolatile memory is ensured. Namely, in the card type storage device comprising the nonvolatile memory, a plurality of data terminals are provided and an interface unit is provided with a circuit for determining levels of data terminals. Some or all of the plurality of data terminals are connected with pull-up resistors for pulling up to a power source voltage. When the determination circuit determines that the data terminals connected with the pull-up resistors are in an open condition, the determination circuit switches a bus width (number of bits) of data.

Multiple field units in a CDMA system are synchronized for communication with a base station using a shared forward and reverse link channel. Each field unit is assigned a time slot in a forward link channel to receive messages from the base station. Likewise, each field unit is assigned a time slot on a common reverse link channel for transmitting messages to the base station. Timing alignment among each of many field units and the base station is achieved by analyzing messages received at the base station in a corresponding time slot from each field unit. Thereafter, a message is transmitted in a corresponding time slot to a particular field unit from the base station for adjusting its timing so that future messages transmitted from the field unit are received in the appropriate time slot at the base station. In this way, minimal resources are deployed to maintain communication and precise synchronization between a base station and each of multiple users, minimizing collisions between field units transmitting in adjacent time slots on the reverse link.

A semiconductor memory device able to read out data at a high speed continuously, provided with, corresponding to a plurality of banks, current address registers for holding addresses for reading data of cell arrays, reserved address registers able to receive in advance and hold reserved addresses for next read operations from the outside, and bank control circuits for making the current address registers hold reserved addresses held in the reserved address registers, making the data be read out, and making the data latch circuits hold the data when the data read out from the cell arrays of the banks by addresses held in the current address registers and held in the data latch circuits become able to be transferred to the outside, and a signal processing system relating to the same.

A method of storing files in a data storage device includes dividing a storage medium of the data storage device into identically sized storage units having a predetermined size, and indicating a status of each storage unit and relating chains of storage units storing a same file in a file allocation table on the storage medium; grouping the storage units into a plurality of groups having a predetermined number of adjacent storage units; assigning a file size classification when creating a file to be stored on the storage medium, the file size classification corresponding to an estimated amount of data in the file to be stored on the storage medium; and allocating at least one of the groups of adjacent storage units for storing the file if the file size classification is greater than a predetermined value.

The disclosure concerns an antenna with open loops and multipath current distribution to achieve ultra wideband characteristics and antenna miniaturization, while simultaneously keeping high performance for a more reliable WAN communication, with higher data transfer, less dropping connections and improved sensitivity. To further reduce spatial requirements, the antenna may be incorporated on a flex substrate for bending with the contour of a device housing or the like.
