An electro-optic display comprises a layer (130) of a solid electro-optic material, at least one electrode disposed adjacent the layer (130) of electro-optic material, and a layer (180) of a lamination adhesive interposed between the layer (130) of electro-optic material and the electrode, the lamination adhesive (180) having a higher electrical conductivity in a direction perpendicular to the layer of lamination adhesive than in the plane of the layer.

An electro-optic display comprises, in order, a backplane comprising a plurality of pixel electrodes; a layer of a solid electro-optic medium; a main adhesive layer; and at least one of a light-transmissive protective layer and a light-transmissive electrically-conductive layer. The electro-optic layer may be in direct contact with the backplane or separated therefrom by a thin auxiliary layer of adhesive. The main adhesive layer may be colored to provide a color filter array. An inverted front plane laminate useful in forming such a display comprises the same layers except that the backplane is replaced by a release sheet. The display combines good low temperature performance and good resolution at higher temperatures.

A random number generator (RNG) resistant to side channel attacks includes an activation pseudo random number generator (APRNG) having an activation output connected to an activation seed input to provide a next seed to the activation seed input. A second random number generator includes a second seed input, which receives the next seed and a random data output, which outputs random data in accordance with the next seed. An input seed memory is connected to the activation seed input and a feedback connection from the activation output so that the next seed is stored in the input seed memory to be used by the APRNG as the activation seed input at a next startup cycle.
摘要:
A braking system for a floor conveyor, which features at least one travel motor for at least one driven wheel, an electric steering control for at least one steered wheel, a service brake with a braking transmitter generating a braking signal and an electromagnetically releasable spring brake as an emergency stop brake, which is amongst others actuable when an error signal is generated in the steering control or a braking signal otherwise, which further features a superordinated vehicle control for various functions of the floor conveyor and a battery for supplying the individual electric consumers, wherein the steering control actuates a first switch at an error signal, which cuts off the electric connection between the battery and the emergency stop brake, wherein an additional switch is connected in series with the first switch and is actuable by a PWM actuator of the vehicle control, and a control line is connected between the steering control and the vehicle control, such that both switches are switched according to the clock of the PWM actuator when an error signal or a braking signal occurs.

Industrial truck, in particular a lift truck, with a drive axle with drive wheels and a drive motor, a steering axle with two steerable wheels, a target value sensor that is connected to a steering wheel, a steering motor, a steering device which is in effective connection with a steering tie rod, a position transducer magnet whose position is recorded by two magnetic resonance sensors that are arranged in parallel, where the position transducer magnet and the resonance sensors are moved relative to each other during a steering movement of the steering device, and where the magnetic resonance sensors generate counter directional analog signals for the actual value of the steering angle of the steerable wheels, a steering control, connected to the target value sensor, the steering motor, and the magnetic resonance sensors, which evaluates the signals received from the target value sensor and the magnetic resonance sensors, and controls the vehicle steering angle to the target steering angle, where the signals of the magnetic resonance sensors are evaluated by the steering control for the recognition of malfunction of one of the magnetic resonance sensors.
摘要:
An access control system and method includes a risk index module which computes a risk index for a dimension contributing to risk. A boundary range defined for a parameter representing each risk index such that the parameter above the range is unacceptable, below the range is acceptable and in the range is acceptable with mitigation measures. A mitigation module determines the mitigation measures which reduce the parameter within the range.

A cutting tool for machining by chip removal has a supply of a cold-gas flow for cooling the immediate machine-cutting region. Accordingly, in this case, the cold-gas flow is supplied internally and is generated by a low-temperature generator, which is integrated into the tool main body and which, via a vortex tube, converts compressed gas from normal temperature into a cold-gas flow and a warm-gas flow.
