摘要:
A regulator circuit includes an OP-amp, buffer, power transistor, voltage divider, load, and feedback current generator. The OP-amp generates first voltage signal by amplifying a difference between an input voltage signal and a feedback voltage signal. The OP-amp drives a first node as the first voltage signal. The buffer drives a second node as a second voltage signal generated based on the first voltage signal. The power transistor includes a drain terminal receiving a supply voltage, a gate terminal connected to the second node, and a source terminal connected to a third node. The voltage divider generates the feedback voltage signal by dividing an output voltage signal of the third node. The load includes a terminal connected to the third node and another terminal receiving a ground voltage. The feedback current generator provides a first feedback current corresponding to a ripple of the output voltage signal to the first node for enhancing a speed at which the ripple reduced.

A method for providing a widget service in a broadcast receiving apparatus is provided. A method for providing the widget service includes operations of receiving widget information, and displaying on a picture-in-picture (PIP) screen at least part of all the received widget information which is to be fitted to the PIP screen, upon occurrence of a preset or trigger event. Therefore, it is possible for a user to construct a sub-screen for providing a widget service by selecting only part of widget information forming the entire display screen rather than reducing the size of the entire display screen.

Provided is a garment for measuring physiological signals. The garment includes at least one electrode sensor, a signal connection line, a snap structure, and a measurement unit. The electrode sensor is coupled to an inner surface of the garment to make contact with a skin for detecting physiological signals. The signal connection line transmits the physiological signals detected by the electrode sensor. The signal connection line is finished against the inner surface of the garment. The snap structure is coupled to a portion of the garment where the electrode sensor is not overlapped and is electrically connected to the signal connection line. The measurement unit is mounted on the snap structure for measuring the physiological signals. The signal connection line has elasticity.

Provided are a physiological signal measurement garment and a physiological signal processing system. The physiological signal measurement garment includes: a main garment body which is formed of an elastic fabric and includes a mesh structure and an elastic band; at least one physiological signal sensing electrode sewn on the garment body; a physiological signal transmission unit which is sewn on the garment body and transmits a physiological signal sensed by the physiological signal sensing electrode; and a physiological information measurement module that measures various kinds of physiological information from the physiological signal, which is sensed by the physiological signal sensing electrode and transmitted through the physiological signal transmission unit. The physiological signal measurement garment is more comfortable for a wearer than similar existing garments and can measure a physiological signal with higher accuracy.
