Abstract:
Lighting control interface techniques and corresponding circuitry are provided. The techniques include receiving a first signal potentially representative of a first lighting control signal, and receiving a second signal potentially representative of a second lighting control signal, and determining if either of the first and second signals complies with a first or second lighting control protocol. The lighting control signal may be applied to the same interface connector (regardless of the protocol), thereby eliminating the need for separate dedicated interface connectors. In some cases, the techniques further include determining that a dummy control signal is manifesting in the first and/or second signals, thereby indicating that no lighting control signal is being applied. Depending on the resulting determination, the techniques may include, for example, setting output lighting power according to a pre-established value, or according to the first or second lighting control protocol.
Abstract:
Methods and systems for converting mechanical oil gauge into an electronic oil gauge. A magnet pairing mechanism and a resistive sensing module are configured to amount to a mechanical oil gauge. The indicator of the mechanical oil gauge moves with the first magnet which cause the second magnet to move on the resistive sensing module which results in changing the resistance of the resistive sensing module at the sliding-to-position, producing an electric signal that is corresponding to the oil level.
Abstract:
Apparatus and methods for storage and transmission of recipe data (process parameters) for the molding of articles in an injection molding apparatus. A controller includes a flow control microcontroller (MCU) that receives recipe data from a recipe storage microcontroller (MCU) mounted to a mold of an injection molding machine, the recipe storage MCU storing the recipe data defining process parameters for the molding of articles in the mold. The flow control MCU executes instructions for controlling valve pin motions according to the recipe data. In one embodiment, a human operator interface is provided for transmitting data to and/or from at least one of the recipe storage and flow control MCU's, allowing the operator to monitor, modify and/or control the process parameters during a molding cycle and/or to create a modified or new recipe for subsequent storage on the recipe storage MCU.
Abstract:
Apparatus and method for detecting a position of an actuator piston driving a valve pin in an injection molding system. The apparatus includes an actuator housing having a body portion, surrounding an axial bore, of a substantially non-magnetic and/or magnetically permeable material, a piston, movable within the axial bore for driving a valve pin, the piston including a magnetic member generating a magnetic field such that axial movement of the piston in the bore modifies the magnetic field according to the position of the piston relative to a detection position, and a magnetic field detector attached to an exterior surface of the body portion at the detection position for detecting the magnetic field associated with the position of the piston and generating an output signal determined by the piston position.
Abstract:
A Wi-Fi ATSC TV Antenna with Waveform Compression is comprised of 5 components—TV antenna, ATSC TV tuner, AD Converter, Waveform Data Compression Unit, and Wi-Fi Transceiver. It is used to transfer Analog RF Waveform to Digital IF Signal over Wi-Fi to a TV-viewing device. It is used for ATSC TV reception devices.
Abstract:
This invention is a method to quickly characterize the time variant channel state information to enable ATSC HDTV signal reception in a mobile environment (e.g. in a moving car, walking, on a bus, etc.) by removing the Doppler interference. The invention relates to a single or multiple antenna ATSC terrestrial DTV receiver for indoor and mobile users.
Abstract:
The present invention provides methods of achieving directed evolution of viruses by in vivo screening or “panning” to identify viruses comprising scrambled AAV capsids having characteristics of interest, e.g., tropism profile and/or neutralization profile (e.g., ability to evade neutralizing antibodies). The invention also provides scrambled AAV capsids and virus particles comprising the same.
Abstract:
Systems, methods, and devices for wireless communication. In one aspect, an apparatus for wireless communication is provided. The apparatus includes a receiver configured to receive a wireless signal comprising a packet. At least a portion of the wireless signal is configured to be received over a bandwidth lower than or equal to 1.25 MHz. The packet is formed from at least one orthogonal frequency-division multiplexing (OFDM) symbol comprising thirty-two tones. The thirty-two tones correspond to frequency subcarriers within the bandwidth. The thirty-two tones of the at least one OFDM symbol are allocated as: twenty-four data tones, two pilot tones, five guard tones, and one direct current (DC) tone. The apparatus includes a processor configured to evaluate the wireless signal. The processor includes a transform module configured to convert the at least one OFDM symbol into a frequency domain signal using a thirty-two point mode.
Abstract:
Methods, apparatuses, and computer program products are disclosed for facilitating decoding a communication received from a wireless terminal. Encoded bits are received from the wireless terminal via a shared uplink channel, and a plurality of acknowledgment tones are identified within the encoded bits. A correlation value is ascertained corresponding to a correlation between detected bits within the plurality of acknowledgment tones and valid bits corresponding to any of a plurality of valid acknowledgment codewords. A determination is then made as to whether the plurality of acknowledgment tones includes information corresponding to a discontinuous transmission by comparing the correlation value to a threshold value.
Abstract:
An apparatus includes an interleaver configured to interleave encoded data and to output a series of interleaved bits to be transmitted via a 1 MHz orthogonal frequency-division multiplexing (OFDM) transmission. The apparatus also includes a modulator configured to modulate the interleaved bits and a transform module configured to transform the modulated bits. A transmit module of the apparatus is configured to transmit the transformed bits included in one or more spatial streams of the 1 MHz OFDM transmission.
