A door system includes a controller for controlling the door system. A user computer system transmits information to the controller over a wireless connection to modify operating parameters for controlling the operation of the door system. During installation of the door system sensors may be utilized to determine if the door system has been installed properly. The sensors may be used to identify if the door system is mounted level and plum, and to review the movement, vibration, speed, acceleration, force, or the like of the sensors, and thus, the components to which the sensors are operatively coupled in order to make adjustments to the door assembly. Furthermore, the operating parameters of the installed door system, may be cloned and provided to other door systems in order to quickly clone and distribute the operating parameters of one or more door systems to one or more other door systems.

A detection sensor or a user device is used to aid in providing authentication and activation of a door system when a user tries to access the door for ingress and egress. Operating parameters of the door systems may be set to allow ingress and egress only when a user is identified and authorized. As such, the operating parameters of the door systems may include authentication and activation parameters such that the door systems are controlled, at least in part, based on the presence of a user and/or a user device and the identification of the specific user. As such operating parameters may be different for different users or types of users. Moreover, the user device may be used to authenticate a user and control ingress and egress through the door automatically or through an authentication action taken by the user.

A device to read data stored on a memory device of a printed circuit board (PCB) while the memory device is installed on the PCB is disclosed, including, a microcontroller to control acquiring memory data from the memory device when a processor on the PCB is in an idle state, and a resistance measurement and signal driver to measure the resistances of the signals controlling a memory device and to read the memory data from the memory. A method and system are also disclosed.

A method of isolating hidden data in a solid state memory system is disclosed including obtaining a logical block address (LBA) image from the memory system, obtaining a physical block address (PBA) image, determining whether an error exists in the PBA image and correcting the error, calculating an ETCRC on each sector of the LBA image and building a search tree indexed on the ETCRC value. For each sector in the PBA image, the method also includes computing an error tolerant cyclic redundancy check (ETCRC) value and searching for the ETCRC value in the LBA search tree. If the ETCRC value is found, also included is comparing the cyclic redundancy check (CRC) of the LBA and PBA sectors, and outputting to an output file the PBA sector as hidden data if either the ETCRC value is not found in the LBA search tree or the CRC comparison fails.

The magnetic pickup response measurement and presentation system quickly measures frequency responses of magnetic pickups under various loading conditions, and the data is presented graphically and aurally to the user to aid user comparison and selection of magnetic pickups for use in musical instruments.

The variable capacitance audio cable allows adjustment of the frequency response of the system in which the cable is used by varying the cable capacitance electronically. This permits musical performers using the cable to tailor the audio response to suit their performance and style.

Variable capacitance audio cable

The cable connection method is a method of connecting to conductors within a triaxial electrical cable, without completely severing the cable, allowing compact, low cost connections to be made while having the added benefit of strain relief of the cable around the connection point and even within the cable itself.

Cable connection method priority

The low capacitance audio connector allows reduction of the interelectrode capacitance through its compatibility with driven shield techniques. This permits an entire audio cable employing these techniques to have very low total capacitance.

An audio power meter includes a circuit for measuring the power of an amplified audio signal outputted by an audio power amplifier to which the audio power meter is connected. The circuit generates an output signal indicative of the power of the amplified audio signal. A first bar display includes a plurality of separately illuminatable segments arranged linearly with respect to one another. Each segment of the plurality of separately illuminatable segments is responsive to the output signal of the circuit and is selectively illuminated in response thereto. When the measured power of the amplified audio signal exceeds a selected threshold power level, the amplified audio signal is attenuated.

A musical instrument tuner includes a means for measuring the frequency of a note played on an instrument, a minimal display means, a means for powering and depowering the tuner, and a means for collecting the signal to be measured. The tuner displays sharp and flat indications to the user, eliminating the ambiguous finite width 'in-tune' window.

An emergency and non-emergency transmitter receivable by broadcast band receivers in nearby vehicles, comprising a first signal generator for simultaneously providing a plurality of selectively spaced carriers having frequency spacings corresponding to the individual channels of the band to be covered and selectively providing amplitude modulation when used for the AM broadcast band, and a second signal generator providing an FM modulated signal, which when combined with the signal from the first signal generator, covers various portions of the FM broadcast band to provide complete coverage thereof. A plurality of signals are generated in a portion of a selected band and modulated, according to the selected band mode, with a pre-stored and selectable voice alarm message. The portion of the band is changed to provide coverage of the entire broadcast band, the broadcast band is also changed, and/or the message is changed to provide effective emergency notification to vehicles and/or listeners within a half-mile radius of the emergency vehicle or public facility issuing the alarm transmission.

Dual-mode transmitter

Wellhead and welder protector comprising an easily erected, temporary shelter designed to envelope a wellhead and the immediate surrounding area of either a production platform, well bay area or jack up rig 'texas deck', for providing an optimal environment for welding, heat treatment, and similar processes. The overhead protection means can be in the form of a horizontal, planar surface comprised of aluminum, galvanized sheet metal, thick fabric or the like, supported via telescopic support means above the wellhead for providing overhead protection for its occupants from overhead falling objects and liquids. Self contained ventilation means for the removal of any toxic fumes and gases associated with welding and related processes is also included. Additionally a new and unique framing system associated with the protection means is used, comprising telescoping support members attached directly to the wellhead to provide ample room in the shelter; the configuration and design of the shelter is such that it is able to withstand the harsh weather such as tropical storms and the like, associated with the offshore drilling environment, yet is lightweight, sturdy, and easily assembled and disassembled.
