Assignee:

iRobot Corporation - Bedford MA

International Classification:

G06F 19/00

US Classification:

700245, 700264, 901 1, 901 47, 3185681, 31856811, 31856812, 34053913, 3405724, 34082549, 342450, 701 23, 701408

Abstract:

A power-saving robot system includes at least one peripheral device and a mobile robot. The peripheral device includes a controller having an active mode and a hibernation mode, and a wireless communication component capable of activation in the hibernation mode. A controller of the robot has an activating routine that communicates with and temporarily activates the peripheral device, via wireless communication, from the hibernation mode. In another aspect, a robot system includes a network data bridge and a mobile robot. The network data bridge includes a broadband network interface, a wireless command interface, and a data bridge component. The data bridge component extracts serial commands received via the broadband network interface from an internet protocol, applies a command protocol thereto, and broadcasts the serial commands via the wireless interface. The mobile robot includes a wireless command communication component that receives the serial commands transmitted from the network data bridge.

Appl. No.:

11/347914

Inventors:

Jason Walker - Somerville MA, US

International Classification:

G01R 11/32

US Classification:

324142000

Abstract:

An improved diagnostic meter, of the type used to measure the conduction of a vacuum tube in an audio power amplifier, which provides a display of the average value of instantaneous power dissipated by the tube. A probe containing a current sense resistor and a voltage attenuator interfaces between the tube and the amplifier to sample current through and voltage across the tube. A multiplier circuit computes a product of the sensed current and voltage, and a low-pass filter computes an average of the product. A display represents the average as a numerical value of Watts dissipated by the tube. A further improvement to the meter incorporates a DC-DC converter into the meter's power supply circuitry which allows the meter to be powered from the AC or DC filament supply provided by the amplifier.

Abstract:

A method for unmanned delivery of an item to a desired delivery location includes receiving, at an unmanned vehicle, first data representative of an approximate geographic location of the desired delivery location, receiving, at the unmanned vehicle, second data representative of a fiducial expected to be detectable at the desired delivery location, using the first data to operate the unmanned vehicle to travel to the approximate geographic location of the desired delivery location, upon arriving at the approximate geographic location of the desired delivery location, using the second data to operate the unmanned vehicle to detect the fiducial; and upon detecting the fiducial, using the fiducial to operate the unmanned vehicle to travel to the delivery location and deliver the item.
