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.

A local workspace access system is associated with a local workspace, reads badge data, and transmits the badge data. A workspace personalization management system receives the badge data, locates an organization associated with the badge data, and transmits the badge data to its associated organization. A server associated with the organization receives the badge data, locates a member of the organization who is associated with the badge data, and transmits the workspace configuration associated with the member to the workspace personalization management system. The workspace personalization management system transmits a keyable code to a messaging service device of the member and transmits the keyable code and the workspace configuration associated with the member to the local workspace access system. The local workspace access system receives member input of the keyable code, and verifies that the inputted keyable code matches the keyable code received from the workspace personalization management system.

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 () which 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.

A keypad capable of being configured with multiple button configurations with buttons of various heights is configured to recognize the button configuration through actuations of the buttons. The keypad is placed in a configuration mode by inputting an unresolvable condition to the keypad. Once in the configuration mode, the buttons are individually actuated in a predefined order to configure the size and function of each button.

A microphone array configurable to connect via an Ethernet connection with an audio processor includes a plurality of MEMS microphones (-), a plurality of sigma-delta modulators (-), a processor and storage (), and an Ethernet physical interface () operating at a network data transmission rate. Each sigma-delta modulator converts the analog output of a corresponding microphone into a bit stream at an audio sampling rate. The processor and storage performs a data-interleaving operation () to combine the bit streams from the sigma-delta modulators into a microphone audio frame serial bit stream (), and loads the microphone audio frame serial bit stream into a FIFO memory () at a FIFO serial data load rate. The processor and storage computes an Ethernet FCS checksum on the microphone audio frame serial bit stream, concatenates, an FCS delay gap, the Ethernet FCS checksum, a timing gap, a frame prefix, a UDP/IP prefix, a payload, and the microphone audio frame serial bit stream to form an Ethernet frame packet serial bit stream, unloads this Ethernet packet serial bit stream from the FIFO memory at the network data transmission rate and transmits the Ethernet frame packet serial bit stream from the Ethernet physical interface.

Microphone array system with Ethernet connection

A system in which a portable electronic device communicates with a keypad including a near field communication (NFC) tag in order to establish remote control of a controllable residential device over a home automation network. Upon placing the portable electronic device near the keypad, a control application running on the portable electronic device is launched and a graphical representation of the keypad is displayed on the portable electronic device. The portable electronic device then provides remote control of the controllable residential device over the home automation network. The portable electronic device may additionally provide expanded control options for the controllable residential device.

Initiating remote control using near field communications

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.

An occupancy sensor detects expected and unexpected occupancies in a monitored area with an expected occupancy schedule. The occupancy sensor includes a real time clock, a memory, a sensor element, a processor, indicator lights and a network interface. The occupancy sensor transmits an occupancy correction signal to a network if the actual occupancy of the monitored area does not match the expected occupancy state of the monitored area.

Digital video data is transmitted from a video source () to a video sink () as a group of three multilevel symbols (, and) per pixel color with each associated symbol being sent at a rate of three times the pixel clock (). When eleven levels are used per symbol () 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.

A commercial airliner () controls and is flown in formation with a drone aircraft () that includes missile detection and diversion equipment () capable of protecting the airliner from a man portable missile ().

Commercial airliner missile protection using formation drone aircraft

A commercial airliner ( ) carries a sensor that detects a characteristic ( ) associated with a man portable missile ( ). Raw sensor data is transmitted via a wireless data-link ( ) to ground stations ( ) 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.

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.
