A word store comprises flip-flops which consist of NAND gates, each flip-flop having two sets of inputs, with a clock and data input for each set, and two separately gated outputs. The first set of inputs and the first output are connected for computer access, while the other inputs and output are connected to peripheral apparatus. The computer may change one or more bits by reading the entire word, modifying individual bits, and writing back the entire word. The peripheral apparatus may set ind...

A magnetic field drive coil arrangement includes a hollow rectangular coil form having a pair of rectangular openings at opposite ends of the longitudinal axis of the form, a first coil wound around the coil form such that the turns of the coil in the central region of the coil form are parallel to the longitudinal axis and a second coil wound over the central portion of the first coil. The portion of the turns of the first coil which are between the access openings and the second coil curve awa...

A cache storage device is provided between a client and a storage device so that an area to be accessed by the client can be locked or excluded in advance.

A method for moving open files on a computer system is disclosed. According to one aspect of the invention, an open file may be accessed by a user while being moved. To ensure accuracy, if data is to be written to an open file while it is being moved, the data is written to both the old and new locations.

A method and system for monitoring the performance of a processor to detect a set of frequently accessed memory items is provided. A memory region to be monitored is selected and divided into an upper half monitored memory region and a lower half monitored memory region. Memory accesses to the upper half monitored memory region and memory accesses to the lower half monitored memory region are counted during a measurable interval. In response to the count of memory accesses to the upper half moni...

A reflection measurement method and apparatus measures reflection characteristics of a device under test (DUT) when access to the DUT is through a dispersive element. The method and apparatus measure a composite reflection response of a network that includes the DUT and the dispersive element coupled to the DUT via a transmission line. A reflection response of the dispersive element is isolated from a remainder of the composite reflection response of the network. A set of transmission parameters...

A system for locating computer documents or data of interest to a user without specification by the user of topics of interest. The system detects the selection of computer documents by the user of the system, and analyzes the contents of the selected computer documents to identify topics to which the contents are related. The system also monitors the user's interactions with the selected computer documents. The system then proceeds without user intervention, using the identified topics and the ...

Expression/person data are obtained and, in turn, are used to obtain information about groups of people in a population. The people access resources that include linguistically analyzable content, such as Web pages that include text. The expression/person data identify, for each of a set of expression types that occur in the resources, people who have accessed resources that include that type. The group information indicates a group of people who have accessed resources that include instances of...

A method, apparatus, and computer-readable media for authorizing users of network portals to access a secure resource hosted by a secure server comprises storing a plurality of user identifiers, each representing a user of an owning portal; storing for each of the user identifiers an access privilege to the secure resource; storing a proxy user identifier representing a guest portal and a guest access privilege to the secure resource for all of the users of the guest portal; receiving from the o...

An improved alarm activation station protector for use with a depressible alarm activating member and which is capable of being accessed by individuals with varying degrees of hand and arm disability. A wall mounted frame member is formed in a generally "U" shape with first, second and third interconnecting sides and a centrally open area for receiving the depressible alarm activating member. A transparent protective cover includes first, second and third sides which slidably engage the frame me...
