Assignee:

Universal Electronics Inc. - Cypress CA

International Classification:

G08C 1900

US Classification:

34082569, 34082522, 34082556, 34082557, 348734

Appl. No.:

10/401378

Inventors:

Kimthoa Thi Nguyen - Anaheim Hills CA, US

Assignee:

Universal Electronics Inc. - Cypress CA

International Classification:

G08C 17/00

US Classification:

341176, 345169, 34082569

Abstract:

A system and method for using an universal remote control to access extended operational functions of a device. A consumer causes the universal remote control to transmit a code data value selected from the library to a target device while observing the effect of the transmitted code data value on the target device. When the target device responds in a manner desired by the consumer, the consumer may tag the code data value that caused the desired effect and assign the tagged code data value to a programmable key on the universal remote control.

Assignee:

Universal Electronics Inc. - Cypress CA

International Classification:

G08B 700

US Classification:

34082569

Abstract:

A system and method for utilizing receiver signal reconstruction characteristics, in combination with a knowledge of code formats being used, to enable a remote control device to learn the coding format of devices operating at high carrier frequencies even though the carrier frequencies cannot be directly measured.

Nov 29, 1993

Appl. No.:

8/158601

Inventors:

Menno Buys - Hengelo, NL
Patrick Hayes - Mission Viejo CA
Kimthoa Nguyen - Yorba Linda CA

Assignee:

Universal Electronics Inc. - DE

International Classification:

G05B 1902

US Classification:

34082522

Abstract:

The remote control comprises: a microprocessor including a CPU and memory; a keypad including several keys coupled to the microprocessor for operating the remote control, some of the keys being a "POWER" key, a "Channel Up" key and a "Channel Down" key; lamp driver circuitry coupled to the microprocessor; structure and program instructions, including said microprocessor, for generating infrared (IR) signals coupled to the IR lamp driver circuitry; and code data for executing command functions for operating a home entertainment device stored in the memory. A power toggle program is stored in the memory for effecting the sending of the IR code for "STANDBY" or the IR code for the number digit "1" each time the power key is pressed. Also a channel rotation program is stored in the memory for effecting the sending of digit number signals in an ascending or descending order number digit each time the "Channel Up" key is pressed or the "Channel Down" key is pressed.

Appl. No.:

8/636666

Inventors:

Patrick H. Hayes - Mission Viejo CA
Kimthoa T. Nguyen - Yorba Linda CA

Assignee:

Universal Electronics Inc. - Twinsburg OH

International Classification:

G08C 1912

US Classification:

341176

Abstract:

A method for selecting a command set from a group of command sets stored in the remote control. Each remote control command set includes a set of commands for operating at least one of various remotely controllable devices. A command, whose effect is observable in the remotely controlled device is assigned to one of the user actuated keys. The keys are pressed one by one until the user observes the desired effect on the remotely controlled device. The user then signals the remote control to exit the select procedure with the remote control setting the remote control to transmit future commands from the command set including the last transmitted effects observable command having the observed desired effect.
