US Patent:

6353403, Mar 5, 2002

Filed:

Apr 6, 2000

Appl. No.:

09/544583

Inventors:

Rodney Owen Williams - Cary NC

Assignee:

Ericsson Inc.

International Classification:

H03M 166

US Classification:

341144

Abstract:

A logic circuit for generating a control voltage includes a ramp DAC and a main DAC. When the control voltage is needed, such as when an associated crystal oscillator is being âturned on,â an input reference voltage is supplied to both the ramp DAC and the main DAC. The ramp DAC generates an output based on the input reference voltage and L supplied control bits for a (preferably short) ramp time period. The output from the ramp DAC is fed to a filter circuit that includes a capacitor to charge the capacitor and the control voltage is generated at least in part from the ramp DAC output as filtered by the capacitor. When the ramp period ends, the state of the input reference voltage is changed and the output from the main DAC, based on the changed input reference voltage and N control bits, is input to the filter. Such a two DAC arrangement allows for a shorter time constant circuit to be employed in association with the ramp DAC and a longer time constant circuit to be employed in association with the main DAC, allowing for quick ramp up of the control voltage.

International Classification:

G01R 3136

US Classification:

702 63, 320106

Abstract:

An information circuit for an input/output pin limited device includes an input/output pin, a first circuit path, and a second circuit path. The first circuit path is responsive to a first excitation on the input/output pin, wherein the first circuit path includes a first component device responsive to a first characteristic of the input/output pin limited device. The second circuit path is responsive to a second excitation on the input/output pin, wherein the second circuit path includes a second component device responsive to a second characteristic of the input/output pin limited device.

International Classification:

H04M 1/00
H04B 1/38

US Classification:

455557, 370908

Abstract:

A wireless communication module for wirelessly communicating with other devices a control pin for controlling at least one function of the communication module, an input device operatively coupled to the control pin, wherein actuation of the input device toggles a signal on the control pin between one of two different states, and a hardware reset circuit configured to implement a hardware reset of the communication module. The control pin is operatively coupled to the hardware reset circuit to at least partially implement the hardware reset, the hardware reset being different from the at least one function.

Appl. No.:

10/873675

Michael D. Townsend - Durham NC, US

Assignee:

Sony Ericsson Mobile Communications AB - Lund

International Classification:

H04B 1/00
H04R 25/00

US Classification:

455 631, 381312, 381331

Abstract:

A mobile station includes an adjustable member for increasing a separation distance between an audio signal output device and an electronic circuit to reduce EMI proximate the audio signal output device caused by the electronic circuit. In one embodiment, the adjustable member comprises a slide member that extends at least a portion of the audio signal output device away from the electronic circuit to increase the separation distance. In another embodiment, the adjustable member comprises a pivot member that rotates the electronic circuit (or audio signal output device) away from the audio signal output device (or electronic circuit) to increase the separation distance. In any event, increasing the separation distance between the audio signal output device and the electronic circuit decreases the EMI proximate the audio signal output device, and therefore EMI effects on external circuits proximate the mobile station, such as a hearing aid.
