Publication number: 20080033310Abstract: A method and an apparatus for indirect, quantitative estimation of beat-to-beat arterial blood pressure utilizing individualized rectifying technology. A function of TK=H(P) that describes the relationship between Korotkoff's sound delay time Tk and cuff pressure P is obtained by measuring different cuff pressures P and the corresponding Korotkoff's sound delay times Tk in a Korotkoff's sound sensor that is distal to the cuff.

Patent number: 5907422Abstract: An optical receiver communication system converts optical signals modulated by analog or digital waveforms to RF signals. The optical receiver contains an automatic level control circuit to adjust the electronic gain of the system across a broad bandwidth spectrum. Two impedance matching circuits are designed using broad band matching technique to expand the bandwidth for increasing the maximum receivable frequencies to 1 GHz. A RLC impedance matching circuit forms a resonant combination to maintain .+-.1 dB fluctuation between the low-and-high-frequency limits of the bandwidth, and a 75.OMEGA. impedance matching circuit creates a 180.degree. phase shift between outgoing and incoming signals to ensure low return loss.Type: GrantFiled: January 6, 1997Date of Patent: May 25, 1999Assignee: Qualop Systems Corp.Inventors: Ching Ho, Yue-Syan Jou, Chun-Meng Su, Peter Wang, Yong Cheng Tu

Patent number: 5398258Abstract: In the present invention a wireless communication system is disclosed. A base unit communicates with a remote unit. The system comprises means for transmitting, using CDMA, between the base unit and the remote unit, in one of a plurality of frequencies channels selected. In one period of time, the base unit transmits and in another period of time, different from the one period, the remote unit transmits. Further, the system comprises means for changing the one frequency channel selected to another frequency channel, different from the one frequency channel, in response to interference in the one frequency channel. Thus, communication between the base unit and the remote unit is then affected over the another frequency channel.Type: GrantFiled: October 26, 1993Date of Patent: March 14, 1995Assignee: Teknekron Communications Systems, Inc.Inventors: Chun-Meng Su, Saman Behtash, Keith Jarett, Huihung Lu, Christopher Flores, David G.

Patent number: 5257265Abstract: For every TDMA block the receiver operation starts with a forward processing procedure and operates on received samples in a first-in first-served order. A sync word detector 32a (see FIG. 4 ) ensures the correct TDMA frame timing and starts the equalizer training. Detected data is stacked in a decision buffer 46. An adaptive equalizer 34a outputs a decision error signal that is used to generate a latch-type loss-of-lock flag. Without loss-of-lock, the receiver works through to the last data symbol and the frame processing is finished.Forward processing is halted and the receiver switches to a backward processing branch if the receiver loses lock midway through the data block. The backward processing branch processes received samples from the input buffer 30 in reverse order. The sync word detector 32b detects the reverse trailing sync word (SYNC #2) and recovers the TDMA symbol timing. The receiver then trains the equalizer and starts data processing in a reverse mode.Type: GrantFiled: August 7, 1991Date of Patent: October 26, 1993Assignee: Pacific CommunicationsInventors: Chun-Meng Su, Chanchai Poonpol, George M.

Patent number: 5247702Abstract: A method of establishing a wireless communication link between a base unit and a remote unit is disclosed. The base unit transmits periodically a sync signal in a first selected time period in a selected frequency channel. The remote unit scans for the clock signal. The remote unit transmits a first response signal encoded by a first code in the selected frequency channel in response to the detection of the clock signal. The first response signal is transmitted in a second selected time period, different from the first selected time period. The base unit transmits a first control signal which is encoded by said first code, in the selected frequency channel, in a third selected time period, which is different from the first and second selected time periods. The first control signal contains a second code to be used in the communication session between the base unit and the remote unit. The remote unit receives the first control signal in the third time period. The remote unit decodes the first control signal.Type: GrantFiled: November 8, 1991Date of Patent: September 21, 1993Assignee: Teknekron Communications Systems, Inc.Inventors: Chun-Meng Su, Saman Behtash, Keith Jarett

Patent number: 5212808Abstract: In the present invention a method of re-establishing a wireless communication after a communication break is disclosed. Prior to the communication break, a base unit transmits to a remote unit a table of channels of communication to be used. The base unit also transmits a clock signal value to the remote unit. After a communication break, the remote unit continues to count the clock signals generated from a clock signal source internal thereto. The remote unit applies a function to the value of the clock signal to obtain an entry in the table. The channel of communication associated with the entry in the table is selected by the remote unit. The base unit continues to count the clock signals generated internal thereto. The base unit applies the same function as the function used by the remote unit to the value of the clock signal to obtain an entry in the table. The base unit selects the channel of communication associated with the entry in the table.Type: GrantFiled: November 8, 1991Date of Patent: May 18, 1993Assignee: Teknekron Communications Systems, Inc.Inventors: Chun-Meng Su, Keith Jarett, Christopher Flores
