Abstract: The use of pre-formed arrays of memristors such as ReRAMs for true random number generation is disclosed. The method exploits the natural randomness in the large stochastic cell-to-cell variations in resistance values at low injected current in the pre-formed range. This novel TRNG scheme can be designed with three interconnected blocks: i) a pseudo-random number generator (PRNG) that is acting as an extended output function (XOF) to generate a stream of addresses pointing randomly at the array of ReRAM cells; ii) a method to read the resistance values of these cells at low injected current and convert the values in a stream of random bits; and, if needed, iii) methods to further enhance the randomness of this stream such as, but not limited to, mathematical, Boolean, and cryptographic algorithms.

Abstract: Systems and methods are disclosed for validating the installation and operation of a fault detection and diagnostic module that monitors a component of an HVAC system. A remote diagnostic server is in operative communication with the HVAC system, and with the fault detection and diagnostic module. A user device communicates data to the remote diagnostic server that defines an association between the fault detection and diagnostic module and the HVAC system. The remote diagnostic server initiates an installation validation by sending a command to the HVAC system that causes the monitored component to initiate an event that is expected to be reported by the fault detection and diagnostic module. For example, a fan motor is turned on. If correctly installed, the fault detection and diagnostic module senses the event, and reports the event to the remote diagnostic server, which confirms the association. The remote diagnostic server sends a message to the user device indicating the result of the validation.

Additional functionality is described that leverages uploaded sensor data. Sensor data may be uploaded to the server in near-real time, and/or buffered locally and uploaded by periodic or episodic, push or pull communication protocols.

Abstract: A method of operating a diagnostic data collection device and a diagnostic data bus for an HVAC system are disclosed. In an embodiment, the diagnostic data collection device includes a diagnostic communication interface and a flexible interface module. The interface module measures electrical properties associated with an HVAC component. Electrical properties may include a sensor output and may include analog and digital signals. The diagnostic data collection device generates an exception message if the sensed property is out of specification. Evaluation rules are provided to detect various types of failures, including transient failures, steady state failures, and trending failures. The diagnostic data collection device self-calibrates by recording electrical properties during normal operation of the HVAC equipment. A plurality of diagnostic data collection devices may be coupled by a diagnostic data bug independent of the HVAC system's control bus, to ensure operational integrity of the diagnostic system.

Abstract: Systems and methods for self-learning fault detection and diagnosis in an HVAC system include a server identifying a fault and one or more predicted causes of the fault based on measurements of operational parameters received from sensors associated with the HVAC system. The operational parameters are compared to evaluation criteria, such as predetermined thresholds, to identify a potential fault. Parameters may be weighted, and optionally scaled to a standardized range to facilitate the diagnosis of HVAC systems of disparate configurations and capacities. Evaluation criteria for each fault are periodically analyzed in view of operational parameter history to identify new criteria having a lower probability of misdiagnosis. Fault detection criteria which are determined to have an unacceptable error rate may be deactivated or flagged for review.

Abstract: Systems and methods for operating a linear motor (e.g., for an ESP), where the motor's mover moves in a reciprocating motion within a bore of the stator. Hard stops are located at the ends of the bore. The motor has a first set of sensors in the stator positioned proximate to the bore. When the mover moves in the bore, the sensors produce corresponding output signals, except when the mover is in a position near, but not in contact with a hard stop. While the sensors produce output signals, the motor is driven in a first direction toward the hard stop. When the sensors stop producing the output signals, the mover has reached the first position, and the motor is controlled to reverse the direction of the mover.

Abstract: A submersible well pump assembly has a pump housing with a pump discharge on upper end. A pump barrel is located within the pump housing, defining an annular passage between the barrel and the pump housing. A plunger is reciprocally carried in the barrel. A motor mounted below the pump housing and operatively couples to the plunger causes the plunger to reciprocate between an upstroke and a down-stroke. A valve and porting arrangement directs well fluid in the barrel below the plunger into the annular passage and out the discharge during a down stroke of the plunger. The valve and porting arrangement admits well fluid into the barrel below the plunger during the up stroke of the plunger. A connecting rod extends between the motor and the plunger. The connecting rod is in tension during the down-stroke.
