Filed:

Apr 24, 2001

Appl. No.:

09/841914

Inventors:

Graham Ross - Poway CA

Assignee:

Hewlett-Packard Company - Palo Alto CA

International Classification:

B41J 2175

US Classification:

347 85, 417 77, 347 89

Abstract:

Embodiments of the present invention comprise fluid pumps having two expandable chambers, with each chamber having a fluid inlet and a fluid outlet. Each chamber further has a pressurizing wall causing the chamber to expand or contract, thus drawing fluid into the chamber or expelling it from the chamber. The pressurizing walls of the two chambers are in mechanical communication, such that when one chamber is expanding, the other chamber is compressing. Multiple check valves prevent retrograde motion of the ink through the pump.

Appl. No.:

12/563986

Inventors:

Graham Ross - Poway CA, US

Assignee:

CareFusion 303, Inc. - San Diego CA

International Classification:

G08B 13/14

US Classification:

3405721, 3405391, 340 101

Abstract:

Methods and systems for monitoring the inventory of products in a storage device that has an antenna are provided, wherein each product has a corresponding wireless tag having a unique wireless tag identification. The inventory monitoring includes accessing an inventory list containing at least one wireless tag identification, sending a specific query via the antenna for each of the at least one wireless tag identifications in the inventory list to the corresponding wireless tag, verifying, in the case that a response is received from the wireless tag corresponding to the wireless tag identification, that the product corresponding to the wireless tag is present in the storage device, determining, in the case that a response is not received from the wireless tag corresponding to the wireless tag identification, that the product corresponding to the wireless tag is not present in the storage device, and updating the inventory list based on the products verified to be present and the products determined to not be present in the storage device.

Inventors:

Mark Yturralde - San Diego CA, US
Graham Ross - Poway CA, US

Assignee:

CareFusion 303, Inc. - San Diego CA

International Classification:

G06F 19/00

US Classification:

235385

Abstract:

A method of tracking an inventory comprises associating a plurality of radio frequency identification (RFID) values corresponding to a plurality of RFID tags with an inventory item, affixing the plurality of RFID tags to a plurality of surfaces of the inventory item such that antenna axes of the plurality of RFID tags are oriented in a plurality of directions, wirelessly sensing RFID tags affixed to items in the inventory using an antenna array comprising one or more antennae, and deciding, if one or more of the plurality of RFID values associated with the inventory item is sensed, that the inventory item is present in the inventory, otherwise deciding that the inventory item is not present in the inventory.

International Classification:

G08B 21/00
H04Q 5/22
H04N 9/74

US Classification:

3406362, 340 101, 348578, 370252

Abstract:

Systems and methods of extending battery life in inventory control devices are disclosed. A passive receiver configured to wirelessly receive an initiation signal having an associated energy field from a remote control system and to output a mode change signal is provided. The passive receiver is configured to be powered by an energy field associated with the initiation signal. A functional module coupled to the passive receiver and configured to be powered by a self-contained power source when the functional module is in an active mode is provided. The functional module is further configured to receive the mode change signal from the passive receiver and to change from an inactive mode to the active mode. The functional module draws more power from the power source in the active mode than in the inactive mode.
