  • Patent number: 10770894
    Abstract: A power loss protection integrated circuit includes a VIN terminal, a VOUT terminal, an STR terminal, a switch circuit (eFuse), a control circuit, and a prebiasing circuit. In a normal mode, current flows from a power source, into VIN, through the eFuse, out of VOUT, and to the output node. A switching converter of which the control circuit is a part is disabled. If a switch over condition then occurs, the eFuse is turned off and the switching converter starts operating. The switching converter receives energy from STR and drives the output node. Switch over is facilitated by prebiasing. Prior to switch over, the prebiasing circuit prebiases a control loop node as a function of eFuse current flow prior to switch over. When the switching converter begins operating, the node is already prebiased for the proper amount of current to be supplied by the switching converter onto the output node.

  • Publication number: 20200247390
    Abstract: A drive force control system configured to reduce a total energy consumption of a hybrid vehicle. The drive force control system calculates: an output power of the engine which can optimize a thermal efficiency given that the engine is operated at a best fuel point; and a required electric power to be supplied from a battery or to be generated by a control motor, which can adjust the drive power established by the output power of the engine to the required power. A power exchange between the control motor and the battery is interrupted if the required electric power to be supplied from the electric storage device or to be generated by the control motor is less than a first predetermined electric power.

  • Publication number: 20200159881
    Abstract: There is a significant precaution when performing random dopant fluctuation by using the drift-diffusion model that is the basis of the conventional device simulation. Because the continuation by a long wavelength approximation was done to derive said drift-diffusion model. That is how to recover the location dependence of discrete impurity ions in the long wavelength approximation. For example, in the case that there is an impurity ion near to the interface to an insulating film, the charge density of an impurity ion, which was made continuous in the conventional method, is unable to catch the charge density change due to polarization at the interface. Because this polarization is dependent of the location of a discrete impurity ion near to the interface.

The authenticated network includes a private key uniquely linked to a public key. The private key is generated by a key generator and an identification device having physical substance and included in an identification core. The private key is regarded as a physical address of the identification core and is confined in the identification core. The public key is publicized as a logical address of a logical node. The logical node and the physical node are uniquely linked by the public key and the private key. The security of the whole network is thus effectively improved.
