US Patent:

6881382, Apr 19, 2005

Filed:

Apr 2, 2002

Appl. No.:

10/114414

Inventors:

Richard A. Goldstein - New York NY, US
Clint Dee Winton Brooks - Sea Bright NJ, US
Lewis Michael Popplewell - Morganville NJ, US

Assignee:

International Flavors & Fragrances Inc. - New York NY

International Classification:

A61L009/03
A61L009/12

US Classification:

422123, 422124, 422125, 116200, 429178

Abstract:

Apparatus and methods for signaling an event using fragrance are disclosed. A fragrance emitting device is activated to a low battery voltage indicator in an electronic device, serving as a warning to replace the battery, either in place of or complimentary to conventional indicators such as warning lights or audible signals. The fragrance emitting system can be integrated into the electronic device itself or can be part of the battery.

Filed:

Appl. No.:

8/550315

Inventors:

Roy Want - Mountainview CA
William N. Schilit - New York NY

Norman I. Adams - Sunnyvale CA

Assignee:

Xerox Corporation - Stamford CT

International Classification:

H04J 316

US Classification:

370236

Abstract:

In a carrier sense multiple-access (CSMA) network, such as a wireless network or a LAN, a transceiver which initiates a transmission to a recipient transceiver in the same medium sends out, prefatory to a bulk of data, a field representative of the length of the data, and another field symbolic of the rate at which the data is to be sent. Non-participant transceivers in the medium receive the data length field and the data rate field, and calculate a length of time they must inhibit themselves to avoid a data collision with the transmitting transceiver, while the participants come to a common agreement at which they can send and receive data.

Abstract:

An IGFET push-pull driver circuit includes an output stage having pull-up and pull-down IGFETs for driving an output node. An inverter stage drives the gate of the pull-up IGFET. A current sensing IGFET biased to represent a resistance is coupled between the pull-up IGFET and the output node to provide a voltage drop which is proportional to the current flowing through the pull-up IGFET. A regulating IGFET with its channel coupled between the gate of the pull-up IGFET and the output node and with its gate coupled to the juncture of the pull-up IGFET and the current sensing IGFET, responds to the voltage drop across the current sensing IGFET to provide feedback control of the conductance of the pull-up IGFET. The maximum output current of the driver is limited to a value which remains substantially constant over a wide range of processing parameters, operating temperature and load impedance.
