Medical image processing system

Abstract: A medical image archiving system and method. A medical image archiving system receives analog NTSC or PAL video from a medical imaging device and converts it to a digital format for storage. The storage can be via local hard disc drive, or CD writer, or other optical storage medium, or via Local or Wide area network storage to a remote electronic storage medium. The system includes an integral web server to permit easy access over a network using a browser. When an image is stored on a CD, it can be stored as a session and the CD closed to prevent further writing.

Wireless headphones for entertainment and telephonic communication

Abstract: A pair of wireless headphones receives radio frequency transmissions from a sound system to provide music and other audio programming to a user who is free to move anywhere within the range of the transmissions. A telephone base unit also broadcasts notification of incoming phone calls to the wireless headphones. The headphones may provide an audio signal over or instead of the audio programming to notify the user of the incoming call. The headphones may also incorporate a microphone so that the user can receive the phone call with the headphones.

Circuit for preventing overcharge and overdischarge of secondary batteries

Abstract: Circuit for preventing overcharge and overdischarge of secondary batteries is disclosed. Overcharge detecting comparators COMP2 and COMP4 each having a hysteresis circuit 1 are connected between positive and negative electrodes of series-connected secondary batteries Abat and Bbat, and overdischarge detecting comparators COMP1 and COMP3 each having a hysteresis circuit 2 are connected also between the above electrodes. Transistors T1, T2 and a resistor R are connected between the batteries for overflow of overcharge and balance of overdischarge. Upon detection of any overcharge by the comparator COMP2 or COMP4, the charge current is interrupted by a transistor T6, and simultaneously the overcharge overflow is discharged by the hysteresis circuit until the battery voltage is lowered to the hysteresis voltage. And after the discharge, the transistor T6 is turned on to resume recharging the batteries. Meanwhile, upon detection of any overdischarge by the comparator COMP1 or COMP3, the discharge current is interrupted by a transistor T5. Thus the overcharge and the overdischarge can be balanced by the hysteresis circuits 1 and 2 respectively.

Image pickup apparatus and synchronization signal generating apparatus

Abstract: An image signal generation portion 11 generates an image signal of a variable frame-rate picked-up image. A signal generation control portion 24 drives the image signal generation portion 11 and generates image pick-up setting information IF to generate an image signal that is frame-synchronized with a generated image signal DVd. The generated image signal DVd is output in condition where the image pick-up setting information IF is inserted in it. When supplied with image pick-up setting information IFex, the signal generation control portion 24 controls the driving operations of the image signal generation portion 11 based on the image pick-up setting information IFex, to frame-synchronize the generated image signal with an image signal of a reference variable frame-rate picked-up image of a source that has supplied the image pick-up setting information IFex. If a plurality of image pick-up devices capable of varying a frame rate is used, the image signals can be frame-synchronized with each other.

Autonomous behavior control architecture of entertainment humanoid robot SDR-4X

Abstract: In this paper we describe the autonomous behavior control architecture of SDR-4X, which serves to integrate multi-modal recognition and motion control technologies. We overview the entire software architecture of SDR-4X, which is composed of perception, short and long term memory, behavior control, and motion control parts. Regarding autonomous behavior control, we further focus on issues such as spontaneous behavior generation using a homeostasis regulation mechanism, and a behavior control/selection mechanism with tree-structured situated behavior modules. In the autonomous behavior control architecture, we achieve three basic requirements, which are the concurrent evaluation of the situation of each behavior module, concurrent execution of multiple behavior modules, and preemption (behavior interruption/resume capability). Using the autonomous behavior control architecture described, we demonstrate that SDR-4X can spontaneously and passively interact with a human.
