Title: Hierarchical data storage system and data caching method
Inventor: NISHIDA YOSHIHIRO
IPC: G06F12/08
Filed: 1999-08-06
Abstract: In a hierarchical data storage system that supplies data, on request, from a library apparatus in which the data are stored on removable media and from a high-speed cache device, the requests are analyzed to select the most frequently requested data and predict the system's least busy periods. During each predicted least busy period, data are copied from the library apparatus to the cache device, if necessary, so that all of the selected most-frequently-requested data are stored in the cache device. Data are not transferred from the library apparatus to the cache device at other times, thereby avoiding unnecessary cache replacements and improving the efficiency with which requests can be served.

Patent CA-2288807-A1 (CA)
Title: Fingerprint reading apparatus
Inventor: AOKI HISASHI
IPC: H05F1/02
Filed: 1999-03-11
Abstract: A two-dimensional photosensor (2) is formed on a surface light source (1), and a transparent conductive layer (3) made of ITO or the like is formed on the two-dimensional photosensor (2). The transparent conductive layer (3) dissipates static electricity and is grounded. Even if a finger in contact with the transparent conductive layer (3) on the two-dimensional photosensor (2) is charged with static electricity, this static electricity can dissipate via the transparent conductive layer (3). When the transparent conductive layer (3) is divided into two layers, and the finger simultaneously touches the two transparent conductive layers, a fingerprint reading start signal is obtained. Even if, therefore, the finger is charged with static electricity, the two-dimensional photosensor can be prevented from malfunction or damage by the static electricity. When a target object in contact between the transparent conductive layers is a copy having a different resistance value, reading is not performed, and the reliability can improve.

Filed: 2000-04-28
Abstract: The present invention relates to radio communications subscriber apparatus and, in particular, although not exclusively, to the installation of equipment for new subscribers to a telecommunications network comprising a fixed wireless access system. An antenna arrangement is disclosed for providing communication links in a fixed wireless access system, the antenna including receiver means including a receive signal demodulator; wherein a signal processing unit receives signals from the received signal demodulator which signal processing unit includes indicators relating to a received signal. The indicators are operable to indicate signal level and some form of signal quality measure e.g. signal vector error, signal to interference or timing stability.  In the alignment phase the processor analyses the received level and quality while the antenna arrangement is scanned across the signal direction (towards the base station in a FWA system). From the stored scan data the processor identifies the best data set and sets an acceptance window. When the antenna arrangement is rescanned the processor identifies when the received signal conditions are within the window. From such an indication the antenna can be secured in a preferred orientation. The invention is applicable to subscriber self-installation.
