摘要： An attenuator having an impedance that is controllable by a first setpoint signal is coupled to a transmission line. A matching circuit having an impedance that is controllable by a second setpoint signal is also coupled to the transmission line. A transformer circuit block also coupled to the transmission line has a complex impedance. A control circuit sets the first and second setpoint signals so as to control a conjugate impedance relationship between the variable impedances presented by the attenuator and matching circuit relative to the complex impedance of the transformer circuit.

摘要： A wearable haptic device includes (a) substrate having provided thereon a fastener (e.g., adhesive) for attachment to a user; (b) one or more EMP transducers attached to the substrate, such that a mechanical response in each EMP transducer may provide a haptic response of sufficient magnitude to be felt by the user; and (c) control circuit controlling the vibration frequency, the time of operation and the duration for each activation of the EMP transducer. The wearable haptic device may include a wireless communication circuit (e.g., Bluetooth transceiver) for receiving message from an external device (e.g., smartphone). The control circuit interprets message received and according to the interpreted message provides an electrical stimulus to cause the mechanical response of the EMP transducer. The EMP transducer may also serve as a sensor, such that a mechanical stimulus on the EMP transducer provides an electrical response that is detected by the control circuit.

摘要： The disclosure relates to a tactile messaging system configured to send tactile messages between users. The system may be configured so a first user may input tactile information into a first wearable tactile user device and a second user may receive sensory output from a second tactile user device that corresponds to the tactile information entered by the first user into the first tactile user device. This may allow users to communicate by touch, without having to manually enter electronic input information into the system.

摘要： A test device contains a data pattern generator for providing a delta-sigma-modulated data stream sampled with a sampling frequency fs at its output. A phase modulator generates a test clock subjected to jitter and having the clock frequency ft at its output. The output of the data pattern generator is connected to a terminal for connection to a data input of a semiconductor component to be tested. The output of the phase modulator is connected to a terminal for connection to a clock input of a semiconductor component to be tested. An evaluation device determines the jitter parameters of the input signal at the input of the data device from the low-frequency component of the input signal. In this case, the low-frequency component contains only frequency components of frequencies which are less than half the sampling frequency fs/2.

摘要： An EMI suppression apparatus allowing a common mode radiant noise energy to be reduced without attenuating a normal mode signal level is disclosed. A communication LSI has an earth terminal connected to the housing via a common mode impedance. A common mode choke composed of two coils having a mutual inductance is provided in the housing. One coil connects a signal terminal of the communication LSI to a signal transmission wire. The other coil connects the earth terminal of the communication LSI to the quasi-ground surface of the housing. The common mode chokes causes a common mode radiant noise generated by the common mode impedance to be removed from the signal transmission wire without affecting a normal mode signal flowing through the signal transmission wire.

摘要： A signal transmission system includes: a switch component, a first choke component, a first conductive path and a second choke component that are connected in series between a power wire and a load; a third choke component and a resonant circuit that are connected in series between another power wire and a common node of the switch component and the first choke component; a second conductive path connected between the load and a common node of the third choke component and the resonant circuit; and a control block. Under control of the control block, a magnetic core of each choke component reaches magnetic saturation when the switch component does not conduct, and operates at magnetic saturation when the switch component conducts.
