A non-transitory machine-readable medium having machine-readable instructions including a firmware generator, the machine-readable instructions for the firmware generator being executable by a processor core to perform operations including signing a firmware image for a hardware security module (HSM) with a private key of a public private key pair to provide a first signature and augmenting the firmware image with a header that includes the first signature to provide an augmented firmware image. The operations further include encrypting the augmented firmware image with a symmetric key to provide an encrypted augmented firmware image. Furthermore, the operations include signing the encrypted augmented firmware image with the private key to provide a second signature and augmenting the encrypted augmented firmware image with the second signature to provide a firmware package for the HSM.

Hardware security module firmware update

A method includes assigning a priority to each of a plurality of protocol activities to produce stack priority information for each of a plurality of protocol stacks. The method further includes dynamically adjusting the priority of each of the plurality of protocol activities in the stack priority information based on a network maintenance activity and based on a rejection or an acceptance of the corresponding protocol activity by a dynamic multi-protocol manager (DMM). The method further includes providing the stack priority information to the DMM.

Priority selection for multiple protocol stacks

An electronic device and methods for providing high resolution ranging measurements are disclosed. The electronic device includes a pulse generator, a memory, an ADC, a timer, a comparator, a processing unit, connectors for coupling to a transceiver and instructions stored in the memory. The instructions, when performed by the processing unit, performs a method that determines an estimated time of arrival of a series of measurement pulses in the signal and turns on, prior to the estimated time of arrival, the ADC to capture the series of measurement pulses using a first resolution provided by sampling the signal at a rate equal to or greater than the Nyquist rate. The ADC remains on for a fixed time period sized to capture the series of measurement pulses.

Methods and electronic device for dynamic distance measurements

A flow meter for determining the flow rate of a fluid through a conduit, including an upper body having an inlet chamber, an acoustic channel, an outlet chamber, a sound wave generator, and a sound wave receiver. The inlet chamber, acoustic channel, and outlet chamber are fluidly connected together and are oriented so as to create a symmetrical fluid pathway through the inlet chamber, the acoustic channel the outlet chamber. The sound wave generator and the sound wave receiver are aligned along a longitudinal axis of the acoustic channel and the sound wave generator is creates a sound wave that moves along the longitudinal axis of the acoustic channel as fluid flows through the acoustic chamber. The receiver detects that sound wave that has moved through the acoustic channel and such information is used to determine the flow rate of the fluid through the flow meter.

Hydraulic system for ultrasonic flow measurement using direct acoustic path approach

A dome-covered rodent trap for capturing rodents. The trap has a base formed of walls and two openings through which rodents may enter. A snap mechanism for trapping rodents is secured to the base. A movable dome also is attached to the base. When the trap is set, the movable dome is maintained in a raised position. However, when the snap mechanism is triggered by a rodent, the movable dome moves downward to cover the base&#x2014;thereby forming a sealed container around a captured rodent.

Dome-covered rodent trap

A flow meter for determining the flow rate of a fluid through a conduit, including an upper body having an inlet chamber, an acoustic channel, an outlet chamber, a sound wave generator, and a sound wave receiver. The inlet chamber, acoustic channel, and outlet chamber are fluidly connected together. The acoustic channel is a non-linear pathway that is symmetrically dimensioned. The sound wave generator is configured to create a sound wave that moves along the liquid pathway formed by the acoustic channel. The receiver detects that sound wave that has moved through the acoustic channel and such information is used to determine the flow rate of the fluid through the flow meter.

Hydraulic system for ultrasonic flow measurement using reflective acoustic path approach

An integrated circuit including a ferroelectric random access memory (FRAM) for storing firmware, and a method of updating that firmware. The FRAM is constructed to selectively operate as a 2T2C FRAM memory in a normal operating mode, and as a 1T1C FRAM memory in an update mode. Updating of the stored firmware is performed by placing the FRAM in its update (1T1C) mode and writing the updated code into alternate rows of the 1T1C half-cells at each of a plurality of memory locations, while the other 1T1C half-cells in the other alternate rows retain the original data. Following verification of the updated contents, the original data in the other half-cells are overwritten with the verified updated data, and the operating mode is changed back to the normal (2T2C) operating mode.

Ferroelectric memory expansion for firmware updates

A memory, such as a non-volatile ferroelectric memory, including both error correction coding (ECC) capability and redundant memory cells. During the system operating life of the memory, upon ECC decoding determining that a symbol read from the memory array at an address cannot be corrected, the failed memory cells are identified, and redundancy enabled to replace those failed cells if available. Redundant columns may be partitioned by row address, to allow the same column of redundant cells to replace bits in different columns for different portions of the memory. Dynamic redundancy is provided by the disclosed embodiments, extending the reliability of the memory during its system operating life.
