Appl. No.:

09/847638

International Classification:

G06F 1206

US Classification:

711113

Abstract:

Methods of caching data in a computer wherein a cache is given a number of caching parameters. In a method for caching data in a computer having an operating system with a file caching mechanism, the file caching mechanism is selectively disabled and a direct block cache is accessed to satisfy a request of the request stream. Cache memory can be expanded by allocating memory to a memory table created in a user mode portion of the computer and having a set of virtual memory addresses. Methods of caching data can include creating an associative map, and optimizing the order of writes to a disk with a lazy writer. Methods are further assisted by displaying cache performance criteria on a user interface and allowing user adjustment of caching parameters such as cache size, cache block size and lazy writer aggressiveness. A user may further be given the ability to enable or disable a cache for a given selected disk volume.

International Classification:

G01S 3/02

US Classification:

342463, 342457

Abstract:

Systems and methods for allowing the location of transmitter to be determined (approximated) without requiring its distance from a receiver to be precisely known. Methods for determining a location of a transmitter without precise distance calculations. In one embodiment, a method is disclosed having the steps of: for a receiver, estimate a first zone a first transmitter is in; for remaining receivers that can receive a given transmitter, each estimate a second zone a first transmitter is in; and determine if there are overlaps in any of the zones. In another embodiment a potential target area is defined wherein the location of a transmitter can estimated.

International Classification:

G06F 17/30

US Classification:

707120, 707 10, 709203, 709219, 3408703

Abstract:

The present invention provides a method of recording object associations using a location system. Object locations are determined based on signals generated from object identifiers linked to the objects and forwarded to an electronic device interfaced with a network. Once the location of the object has been determined, the location determining module consults a database to determine associations between the located object and other objects or specified locations based on the other objects proximity to the located object. Once an association is determined, it is stored and the duration of the association is subsequently recorded. The data from the identified associations may then be leveraged in a number of ways as input data for a variety of applications, such as billing software, equipment utilization software, asset management software, and automatic event generation software.

Abstract:

A system, method, and processor readable medium containing code embodied therein are provided that enable system users to view one or more system user's status and to establish communications with the one or more system users using a user indicator in an electronic document (e. g. , electronic mail message, hypertext markup language document). The user indicator may be a system user's login identification presented as a hypertext link to one or more communication options. The system may include an identification module for identifying the one or more system users. The identification module may identify a system user's login identification (e. g. , the system user's name, employee number) and provide the system user's status using the user indicator. A status module, responsive to the identification module, provides the status of the system users. The status module may provide a visual indication of a system user's status using, for example, color coding, formatting, symbols, etc.

Appl. No.:

10/970193

Inventors:

Michael K. Dempsey - Westford MA, US

Assignee:

Radianse, Inc. - Andover MA

International Classification:

H04M 11/04

US Classification:

4554041, 4554042, 4554561

Abstract:

Systems, methods and computer program products for accurately determining the location of people or objects are disclosed. The location of people or objects is calculated based on a received signal strength indication (RSSI). The distance between a transmitter and a receiver is calculated in a manner that can reduce or eliminate the effect of multiple paths of a signal between the transmitter and the receiver. Therefore, the location system provides a mechanism for determining the RSSI value accurately regardless of the multiple paths between a transmitter and receiver.

Abstract:

A system and a method for detecting if a person has fallen down is provided. The system includes at least two sensors which remotely detect energy in at least two zones. The output of the sensors are analyzed and compared to characteristics which are determined to be representative of a fall. If the sensor outputs match the particular characteristics, the system concludes that a fall has occurred and outputs this result. An alarm may be generated if the system detects a fall.
