Systems and methods for securing a select vehicle's automotive controller network are described. Embodiments introduce a pass-through security module with a first interface physically coupled to an unsecured access port to the automotive controller network and configured to communicatively couple or decouple with the access port based on a determination of whether network access requests received by a second interface of the security module from an external device are authorized to interact the automotive controller network. Authorization determinations may be made by the security module in conjunction with a telematics control unit and/or a remote server in accordance with one or more security policies. The security module may further use the one or more security policies to impose an encryption infrastructure on the automotive controller network to facilitate sender identification and data frame authenticity.

The control device automatically turns the power switching circuit “OFF” whenever the load current exceeds a first value or the current squared time value exceeds a second value or an “OFF” signal is received from the one or more data interfaces, and automatically turns the power switching circuit “ON” whenever an “ON” signal is received from the one or more data interfaces.

A solid-state memory in which each memory cell includes a cross-point addressable write element. Each memory cell includes a storage element, such as a pair of cross-coupled inverters, and a read buffer for coupling one of the storage nodes to a read bit line for the column containing the cell. The write element of each memory cell includes one or a pair of write select transistors controlled by a write word line for the row containing the cell, and write pass transistors connected to corresponding storage nodes and connected in series with a write select transistor. The write pass transistors are gated by a write bit line for the column containing the cell. In operation, a write reference is coupled to one of the storage nodes of a memory cell in the selected column and the selected row, depending on the data state carried by the complementary write bit lines for that column.

A static RAM redundancy memory for use in combination with a non-volatile memory array, such as ferroelectric RAM (FRAM), in which the power consumption of the SRAM redundancy memory is reduced. Each word of the redundancy memory includes data bit cells for storing addresses of memory cells in the FRAM array to be replaced by redundant elements, and also enable bits indicating whether redundancy is enabled for those addresses. A logical combination of the enable bits in a given word determines whether the data bit cells in that word are powered-up. As a result, the power consumption of the redundancy memory is reduced to the extent that redundancy is not enabled for segments of the FRAM array.

Method for control of synchronous electrical motors with application for stepper and Brush-Less Direct Current motors for which there is an explicit relation between the active electrical power supplied to the motor and the mechanical power that the motor delivers to the load. The active electrical power Pel consumed by the motor is measured and according to FIG. 3 the mechanical power Pmech and the maximum available mechanical power Pmech max are determined. The ratio between Pmech and Pmech max is calculated and is compared to the set value of the same ratio. If it is greater than the set one either the operating currents are increased either the operating speed is decreased or both operations are executed. But if it is smaller—either the operating currents are decreased either the operating speed is increased or both operations are executed.
