A method and an arrangement are provided for scalable confocal interferometry for distance measurement, for 3-D detection of an object, for OC tomography with an object imaging interferometer and at least one light source. The interferometer has an optical path difference not equal to zero at each optically detected object element. Thus, the maxima of a sinusoidal frequency wavelet, associated with each detected object element, each have a frequency difference Δf_Objekt. At least one spectrally integrally detecting, rastered detector is arranged to record the object. The light source preferably has a frequency comb, and the frequency comb differences Δf_Quelle are changed in a predefined manner over time in a scan during measuring. In the process, the frequency differences Δf_Quelle are made equal to the frequency difference Δf_Objekt or equal to an integer multiple of the frequency differences Δf_Objekt at least once for each object element.

A synchronous memory device having at least one memory section which includes a plurality of memory cells. The memory device comprises a register to store a value which is representative of a delay time after which the memory device responds to a read request and clock receiver circuitry to receive first and second external clock signals. The memory device also includes an output driver(s) to output data on a bus, in response to a read request and in accordance with the delay time, wherein a first portion of the data is output synchronously with respect to the first external clock signal and a second portion of the data is output synchronously with respect to the second external clock signal. The memory device may include a delay locked loop to generate internal clock signal(s) using the external clock signal(s). The output drivers output data on the bus in response to the internal clock signal(s). The memory device may include input receiver circuitry, coupled to the bus, the receive the read request, wherein the read request is sampled from the bus synchronously with respect to the first external clock signal.

Data access operations in a database system may be accelerated by allowing the memory cache to be supplemented with a disk cache. The disk cache can store data that isn't able to fit in the memory cache and, since it doesn't contain the primary copy of the data for the database, may organize the data in such a way that the data is able to be streamed from the disks in response to data read operations. The reduced number of read data operations allows the data to be read from the disk cache faster than it could be served from the primary storage facilities, which might not allow the data to be organized in the same manner. The cache hit ratio may be increased by compressing data prior to storing it in the cache. Additionally, where a particular portion of data stored on the disk cache is being used heavily, that portion may be pulled into memory cache to accelerate access to that portion of data.

The cradle and the primary wireless communication device may be releasably joined together so as to form a unitary structure when contacting the body. Alternately, the cradle may interface with the body, and communicate wirelessly to the primary wireless communication device. A cradle adapted to provide for a portable electrocardiogram includes a plurality of electrodes adapted for contact or non-contact sensing of the body. In the preferred embodiment, three electrodes are arranged in a triangular arrangement, most preferably a Einthoven triangular arrangement, with the distance between electrodes being 4 centimeters or less.

Disclosed is a method of capturing and reading a pattern image having three or more pages generated from predetermined information using a capturing section provided in a reading apparatus. The pattern image is configured such that each page includes relevant page information indicating a position of the relevant page and the pages are displayed on a display screen sequentially and successively at a time interval and cyclically and repetitively. The method includes a step of, when two pages of the pattern image have been read, causing the reading apparatus to predict a capturing timing by the capturing section for each remaining unread page from a capturing time interval between the two pages and the relevant page information of each of the two pages, and to perform control such that each remaining unread page of the pattern image is captured and read by the capturing section with the predicted capturing timing.

The balance of funds remaining for a stored-value card (“SVC”) may easily be determined without going through an actual purchase transaction with the SVC. The balance is obtained wirelessly from a server storing information pertaining to SVCs, and may be provided in a discreet manner. A card reader adds a card security code to a card number read from the SVC, and encrypts the card number and the CSC. The encrypted information is wirelessly sent to a cellular telephone. The cellular telephone decrypts the encrypted information and wirelessly transmits a balance-information request, which includes the card number and the CSC, to the server. The server receives the request and wirelessly sends the requested balance information to the cellular telephone and, in turn, the cellular telephone wirelessly sends the requested balance information to the card reader, which provides the information to the requester.

A combination of a host system and a storage system is disclosed that facilitates improved responsiveness of the host system to user requests. In one embodiment, the host system includes a cache management module, a partitioning module, and a driver. The cache management module determines write data to cache to a dedicated zone of a hard disk media of the storage system. The partitioning module partitions the hard disk media into one partition including the dedicated zone and another partition not including the dedicated zone. The driver transmits storage access commands to the storage system to cache data in and retrieve cached data from the one partition. Thereby, the host system can access the write data from the hard disk media more quickly than if the write data were cached in and accessed from another zone of the hard disk media.

A non-volatile storage device (1) has non-volatile memory units (FARY0 to FARY3), buffer units (BMRY0 to BMRY3) and a control unit (CNT), and the control unit can control a first access processing between an outside and the buffer unit and a second access processing between the non-volatile memory unit and the buffer unit upon receipt of directives from the outside separately from each other. The control unit can independently carry out an access control over the non-volatile memory unit and the buffer unit in accordance with the directives sent from the outside, respectively. Therefore, it is possible to set up next write data to the buffer unit simultaneously with the erase operation of the non-volatile memory unit or to output once read storage information to the buffer unit at a high speed as in a cache memory operation in accordance with the directive sent from the outside. Consequently, it is possible to reduce the overhead of a data transfer for reading/writing data from/to the non-volatile storage device.

A character reading system efficiently and quickly applies an optical verification process to detect magnetic ink character misreads. In the system, a magnetic ink character reading device reads magnetic ink characters on a processed medium and generates magnetic ink character data, an image reading device scans an image of the processed medium and generates image data, and a position calculator calculates positions of magnetic ink characters on the processed medium and generates magnetic ink character position information. A communication controller sends the magnetic ink character data, image data, and magnetic ink character position information to a host device which includes an optical recognition device that optically recognizes select magnetic ink characters from the image data based on the character position information. By selectively applying optical verification (e.g., only when character misread by the magnetic reading device is high), verification is required less frequently and high speed processing is enabled.
