Magnetic sensors with magnetic field immunity are disclosed. In one aspect, a magnetic sensor includes an array of magnetic sensor cells. Each of the magnetic sensor cells includes a magnetic field source, and a plurality of magnetoresistive (MR) sensors arranged in a bridge circuit. The bridge circuit is configured to output a signal indicative of a force applied to the magnetic sensor based on movement of the magnetic field source relative to the MR sensors. The MR sensors are arranged such that the signal output by the bridge circuit is substantially unaffected by an external magnetic field.

The present disclosure relates to interleaved analog-to-digital converters (ADCs) that can provide an analog finite impulse response anti-alias filter. The analog finite impulse response anti-alias filter can have an impulse response duration that is longer than an interleaving time conversion window of an individual interleaved ADC of the interleaved ADC.

Techniques are described to control the quantizer clock edge to adjust a delay of the feedforward path, which includes the quantizer and the digital-to-analog converter (DAC), to sustain matching over varying clock frequencies as well as over process, voltage, and temperature (PVT). A digitally controlled phase/time delay generating block may be used to control the quantizer clock edge, in an open loop or within a feedback loop, to provide the required time delay or advancement. Calibrations may be performed in the foreground and/or background. Using various techniques, the delay element design may focus on accurate wideband matching without focusing on tunability over varying clock frequencies.

Disclosed is an excavator comprising: a ground engaging structure comprising a pair of track assemblies for propelling and steering the excavator; a rotatable superstructure mounted to the ground engaging structure; a working arm mounted to the rotatable superstructure, the working arm comprising one or more hydraulic actuators arranged to operate the working arm; a hydraulic pump in hydraulic flow communication with the one or more tracks and/or the one or more hydraulic actuators; a hydraulic tank connected to the hydraulic pump; at least one electric motor configured to drive the hydraulic pump to provide a flow of hydraulic fluid to propel the one or more track assemblies and/or operate the hydraulic actuators; at least one battery for providing electrical power to the hydraulic pump; and, at least one electrically operated fan configured to provide a flow of cooling air onto the hydraulic tank to cool the hydraulic fluid therein.

The present disclosure provides a nitrogen removal unit (NRU) for removing nitrogen from a LNG feed stream. The NRU employs a nitrogen stripping column and a nitrogen removal column to cooperatively remove nitrogen from the LNG. An overhead stream of nitrogen-containing LNG from the nitrogen stripping column is directed to the downstream nitrogen removal column for further nitrogen removal. The nitrogen removal column outputs a nitrogen-rich overhead stream that can be vented to the atmosphere or processed into a usable end product, and a methane-rich bottom stream that is supplied to the nitrogen stripping column as methane-rich reflux. A denitrogenated LNG bottom stream from the nitrogen stripping column may be directed to one or more storage tanks. The NRU may be a subsystem of a LNG plant.

A floor system for a building, the floor system comprising: a first layer defining an upper surface and comprising a first material; a connecting assembly connected to the upper surface of the first layer, said connecting assembly configured for connecting a component to the floor system; a heating arrangement located above the upper surface of the first layer for providing thermal energy to the floor system; a second layer located on top of the upper surface of the first layer, wherein the connecting assembly comprises a connector body connected to the first layer and an elongate mounting member extending from the connector body for connecting a component thereto, wherein a length of the mounting member is greater than a thickness of the second layer such that a portion of the mounting member protrudes from an upper surface of the second layer.

Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product aspects, and/or combinations and sub-combinations thereof, for enhancing images and/or videos captured by a camera. An example aspect operates by receiving, by at least one computer processor on the camera, a video frame including a first set of pixels. The method further includes performing the video processing on the first set of pixels to generate a second set of pixels before compressing or encoding the received video frame. The method further includes compressing the second set of pixels and causing the compressed second set of pixels to be displayed on a display device.

The present invention discloses methods and systems, modules and cellular application for controlling a parking lot of limited access. It comprises a detector configured for proving an identifying signal of either or both vehicle and its driver/passenger to be parked in said parking lot; an identifying signal processing module configured for identifying said identifying signal of either or both vehicle and its driver; a gate arrangement configured for reversibly blocking and unblocking an access of unauthorized vehicles to said parking lot; optionally, a motion detector intercommunicated with said detector; a schedule unit configured for time managing parking lot occupancy; a database of either or both time-resolved "allowed and "NOT-allowed" identifications belonging to vehicles authorized at said parking lot; and a controller configured for receiving either or both vehicle and its driver/passenger, interrogating said database and configured for, if said identification is "allowed" at a relevant time-period, commanding said gate arrangement to unblock said access; and if said identification is "NOT-allowed" at said relevant time-period, commanding said gate arrangement to block said access.

A power disconnect switch may include a first terminal configured to couple to a boost converter output and a second terminal configured to couple to a load. A comparator may include a first input terminal configured to couple to a source input, a second input terminal configured to couple to the boost converter output, and a first output terminal configured to output a signal indicating a condition of the boost converter output being less than or equal to the source input. A control circuit may include an input terminal coupled to the first output terminal of the comparator and a second output terminal coupled to the power disconnect switch. The control circuit may be configured to open the power disconnect switch in response to receiving the signal indicating the condition.

Apparatus and methods for compact transmission lines are disclosed herein. In certain embodiments, a transmission line includes a pair of coupled lines including a first conductive line that is electromagnetically coupled to a second conductive line. A first port is electrically connected to a first end of the first conductive line, while a second end of the first conductive line is electrically connected to a first end of the second conductive line. Additionally, a second port is electrically connected to a second end of the second conductive line such that the transmission line is provided between the first port and the second port.
