International Classification:

G06F 19/00
H04W 48/00

US Classification:

700245, 700249, 700264, 370351, 709223, 709229, 713153, 340 35

Abstract:

A robot system includes a base station and a robot. The base station includes a wireless transceiver configured to communicate TCP/IP transmissions over a local wireless protocol, a wired Ethernet connector for communicating TCP/IP transmissions over a local wired Ethernet accessing the Internet, and an access point circuit for transferring TCP/IP transmissions between the local wired Ethernet and local wireless protocol. The access point circuit is limited to a predetermined IP address locked to the robot, a predetermined shell level encryption locked to the robot, and predetermined ports to the Internet open only to the robot. The robot includes a wireless transceiver configured to communicate TCP/IP transmissions over a local wireless protocol and a client circuit for transferring TCP/IP transmissions over the local wireless protocol.

Abstract:

A mobile robot guest for interacting with a human resident performs a room-traversing search procedure prior to interacting with the resident, and may verbally query whether the resident being sought is present. Upon finding the resident, the mobile robot may facilitate a teleconferencing session with a remote third party, or interact with the resident in a number of ways. For example, the robot may carry on a dialogue with the resident, reinforce compliance with medication or other schedules, etc. In addition, the robot incorporates safety features for preventing collisions with the resident; and the robot may audibly announce and/or visibly indicate its presence in order to avoid becoming a dangerous obstacle. Furthermore, the mobile robot behaves in accordance with an integral privacy policy, such that any sensor recording or transmission must be approved by the resident.

International Classification:

H03L 7/06

US Classification:

327156, 327157, 327148, 375376

Abstract:

Described is a frequency synthesizer having a wide output frequency range and small frequency tuning steps. In-band spurious components are maintained at low levels and phase noise is significantly reduced. The frequency synthesizer can be fabricated as an integrated circuit device having a small area and low power dissipation. The frequency synthesizer can be used in wideband frequency systems to reduce cost and size by replacing multiple frequency synthesizers each devoted to a portion of the overall system frequency range.

Assignee:

International Classification:

G06F 19/00

US Classification:

700245

Abstract:

A robot obstacle detection system including a robot housing which navigates with respect to a surface and a sensor subsystem aimed at the surface for detecting the surface. The sensor subsystem includes an emitter which emits a signal having a field of emission and a photon detector having a field of view which intersects the field of emission at a region. The subsystem detects the presence of an object proximate the mobile robot and determines a value of a signal corresponding to the object. It compares the value to a predetermined value, moves the mobile robot in response to the comparison, and updates the predetermined value upon the occurrence of an event.

International Classification:

G06F 15/173

US Classification:

709224, 709223

Abstract:

A website test environment invokes multiple instances of a commercial browser, and captures invocations of browser operations for gathering performance data without interference from other instances or multiple occurrences of the operating system (OS). Commercial browsers often employ constraints that assume only a single instantiation is executing on a particular machine. Configurations allow each instance to present as a separate user, thus avoiding conflicts that may arise from temporary files and network connections, for example. Each browser instance operates as a performance agent and dynamically links with a set of entry points for accessing performance related browser operations. As each agent invokes native (OS specific) machine functions for network access via particular entry points, configurations disclosed herein redirect the entry points to a collection layer of instructions (code) for capturing performance data in addition to invoking the native OS function called for by the browser operation.
