Publication number: 20230012542Abstract: An innovative system for transmitting encrypted 1-bit audio over an Ethernet network comprises using an omni-directional micro-electrical-mechanical system acoustic sensor element to provide an analog input signal to a sigma-delta modulator that then creates a pulse density modulated 1-bit data stream, at an audio oversampling rate, to a first input of a first exclusive-or (XOR) logic gate. The second input of the XOR logic gate is simultaneously presented with a first pseudo-random 1-bit data stream, at the same audio oversampling rate, thereby resulting in an encrypted pulse density modulated (PDM) 1-bit data stream at the output of the XOR logic gate. The encrypted PDM 1-bit data stream is clocked into a first-in first-out (FIFO) memory at the audio oversampling rate and is clocked out of the first FIFO memory as Ethernet PDM frame data packages at a predetermined Ethernet PHY transfer rate.Type: ApplicationFiled: September 16, 2022Publication date: January 19, 2023Applicant: Crestron Electronics, Inc.Inventor: Philip L.

Patent number: 11451526Abstract: An innovative system for transmitting encrypted 1-bit audio over an Ethernet network comprises using an omni-directional micro-electrical-mechanical system acoustic sensor element (11) to provide an analog input signal (33) to a sigma-delta modulator (12) which then creates a pulse density modulated 1-bit data stream (32), at an audio oversampling rate, to a first input of a first exclusive-or (XOR) logic gate (58). The second input of the XOR logic gate is simultaneously presented with a first pseudo-random 1-bit data stream (78), at the same audio oversampling rate, thereby resulting in an encrypted pulse density modulated (PDM) 1-bit data stream (73) at the output of the XOR logic gate. The encrypted PDM 1-bit data stream is clocked into a first-in first-out (FIFO) memory at the audio oversampling rate and is clocked out of the first FIFO memory as Ethernet PDM frame data packages (74) at a predetermined Ethernet PHY transfer rate.Type: GrantFiled: April 10, 2020Date of Patent: September 20, 2022Assignee: Crestron Electronics Inc.Inventor: Philip L.

Patent number: 8798189Abstract: A system for communicating data comprises a clock channel configured to transmit a clock signal at a predetermined rate and at least one data channel configured to transmit data as a sequence of blocks of multi-level symbols being sent at a fixed multiple of the clock rate. Each block of multi-level symbols comprises a sequence of at least three multi-level symbols. Each multi-level symbol has an analog voltage level selected from a predetermined number of possible values, the predetermined number being an integer greater than two. The fixed multiple of the clock rate is an integer greater than one.Type: GrantFiled: November 10, 2011Date of Patent: August 5, 2014Assignee: Crestron Electronics Inc.Inventor: Philip L. Kirkpatrick

Patent number: 8081705Abstract: Digital video data is transmitted from a video source (61) to a video sink (62) as a group of three multilevel symbols (611, 612, and 613) per pixel color with each associated symbol being sent at a rate of three times the pixel clock (601). When eleven levels are used per symbol (611) and undesirable symbol groups having excess DC residual or minimal energy are eliminated, and a built-in-test symbol group is added for pixel alignment; there results a one-to-one correspondence between the remaining symbol groups available and the two-hundred and sixty possible states that are used in the TMDS physical layer that is in widespread commercial use.Type: GrantFiled: June 27, 2008Date of Patent: December 20, 2011Assignee: Crestron Electronics Inc.Inventor: Philip L.

Patent number: 6738012Abstract: A commercial airliner (10) carries a sensor that detects a characteristic (21) associated with a man portable missile (20). Raw sensor data is transmitted via a wireless data-link (41) to ground stations (31-33) that process the airliner transmission and determine both the presence of the missile and a precise aircraft position. Countermeasures are fired to detonate within a close proximity of airliner in order to divert the detected missile.Type: GrantFiled: May 2, 2003Date of Patent: May 18, 2004Assignee: Honeywell Industrial Inc.Inventor: Philip L.

Patent number: 6559933Abstract: A robot sentry with a scanning laser observes the sky just above the geographic skyline looking for a vertical airflow pattern characteristic of the rotor inflow to a helicopter rotor. The presence of this vertical airflow pattern indicates the probable presence of a reconnaissance helicopter that is using terrain masking.Type: GrantFiled: December 6, 2001Date of Patent: May 6, 2003Assignee: Honeywell International Inc.Inventors: Philip L. Kirkpatrick, Richard P. Krulis
