US Patent:

20140114739, Apr 24, 2014

Filed:

Oct 23, 2013

Appl. No.:

14/061583

Inventors:

Mohammed Nazrul ISLAM - Jamaica NY, US

International Classification:

G06Q 30/02

US Classification:

705 1439

Abstract:

A company's coupons or advertisements can be posted on a social business network. A company needs to be registered first with the social business network before it can post its coupons and advertisements; while a consumer can view the coupons and advertisements freely with no requirement of registration. The company can either fill a coupon request form to make the network to generate a coupon for it, or create a coupon themselves and then upload it to the network. The registered company can also post its advertisement. Before anything is posted on the website, it will be reviewed to make sure its content is appropriate. The method also allows a company to purchase a time slot to use a live video screen for marketing.

Appl. No.:

11/871100

Inventors:

Joseph S. Elder - Orlando FL, US
Joseph T. Yestrebsky - Apopla FL, US
Mohammed D. Islam - Winter Park FL, US

Assignee:

Micrel, Incorporated - San Jose CA

International Classification:

H04B 1/28

US Classification:

455333

Abstract:

A single chip superhetrodyne AM receiver is disclosed herein. To compensate for process variations in the implementation of the IC, bias currents setting the operating conditions for various amplifiers and other components in the system are adjusted based on frequency control signals in a PLL circuit in the local oscillator. Since the magnitude of the control signal reflects the process variations, the bias currents are adjusted based on the control signal to offset these variations in other portions of the receiver. To further improve the signal to noise ratio of the receiver, the IF filter is tuned within a range so as not to include any integer multiple or integer divisor of the timing reference frequency. Various techniques are described for enabling a complete superhetrodyne AM receiver to be implemented on a single chip which receives an antenna input signal and outputs a digital data signal.

International Classification:

H04B 1/28

US Classification:

455255000, 455333000

Abstract:

A single chip receiver is disclosed herein. The chip only requires an external antenna for operation. A decoder is formed on chip for performing logical operations on demodulated digital data. A baseband filter is controlled by external control signals to have one of a plurality of discrete frequency response bandwidths depending on the type of signal to be received. To compensate for process variations in the implementation of the IC, bias currents setting the operating conditions for various amplifiers and other components in the system are adjusted based on frequency control signals in a PLL circuit in the local oscillator. Since the magnitude of the control signal reflects the process variations, the bias currents are adjusted based on the control signal to offset these variations in other portions of the receiver.
