2797 results about "Start signal" patented technology

In telecommunication, a start signal is a signal that prepares a device to receive data or to perform a function. In asynchronous serial communication, start signals are used at the beginning of a character that prepares the receiving device for the reception of the code elements.

Robot cleaner, system employing the same and method for re-connecting to external recharging device

A robot cleaner capable of returning to an external recharging device. The robot cleaner includes a driving portion for driving a plurality of wheels, at least one camera installed on a body of the robot cleaner, the camera for photographing external surroundings, and a controller for photographing an image through a camera for recognition of a connection position where the external recharging device is connected with the robot cleaner and stores the photographed image, and controls the driving portion so that the robot cleaner can move from the external recharging device to a destination when an operation start signal is received in the robot cleaner connected to the external recharging device, and for tracing a path to the connection position of the external recharging device and the robot cleaner during a robot cleaner's return to the external recharging device while comparing a current image currently taken by the camera with a stored image of the connection position of the robot cleaner and the external recharging device. Returning of the robot cleaner is carried out when the robot cleaner, separated from the external recharging device, completes its job or needs a recharging, by using the previously stored image and an image currently taken by the camera. Accordingly, an error in the location process, mainly caused due to external interference signals, is decreased, and errors in tracing a path and connecting to the external recharging device can also be decreased.

Remote operation apparatus, operation target apparatus, method for controlling remote operation apparatus, method for controlling operation target apparatus, and remote operation system

A remote operation apparatus (300) includes: an operating-side first communication section (301) that is capable of transmitting a signal to an operation target apparatus (200); an operating-side second communication section (302) that is capable of transmitting/receiving the signal to/from the operation target apparatus (200); a connection start section (11) which transmits a connection start signal, which notifies a start of the transmission/reception of the signal via the operating-side second communication section (302), to the operation target apparatus (200) via the operating-side first communication section (301); and an operating-side communication control section (12) which transmits/receives the signal to/from the operation target apparatus (200) via the operating-side second communication section (302). With this arrangement, it is possible to easily specify a communication partner to/from which a signal is transmitted/received via the operating-side second communication section (302). Moreover, an amount of data transmitted by the operating-side first communication section (301) can be suppressed to a bare minimum. That is, it is possible to easily specify a communication partner and to suppress an amount of data transmitted by communication means for specifying the communication partner to a bare minimum.

Intelligentized rehabilitation training equipment for hand functions of patients suffering from cerebral injury

The invention relates to hand function rehabilitation training equipment based on a spontaneous movement imagery electroencephalograph. Hardware of the instrument consists of an electroencephalograph signal acquisition and processing module, a hand force signal real-time detection sensor array, a control module based on multisource information fusion and a rehabilitation manipulator module, and software for supporting the active rehabilitation training of hand functions is arranged in a computer. The rehabilitation training equipment provides external compensation assistance or resistance hierarchically by taking movement imagery electroencephalographs of patients who suffer from cerebral injury as a starting signal and the muscle force of hands as a feedback signal in a self-adaptive mode according to the myasthenia state of the patients to assist patients who suffer from dyskinesia in performing passive, assisted and active rehabilitation training, displays the state information of the hand movement functions and the provided external power information for doctors and the patients and provides an objective and quantitative assessment method and an index for clinical rehabilitation diagnosis and treatment. The instrument is easy to use, has a friendly interface and is accepted by the doctors and the patients easily. A user can operate a system of the instrument without programming experiences, and the operating environment is not complex.

Small low-altitude light area array laser radar measuring system

The invention discloses a small low-altitude light area array laser radar measuring system. The master control sub-system of the measuring system triggers a pulse laser emitting module to emit lasers, the lasers are collimated and generate two paths of laser signals through a beam splitting sheet, one path is used for determining the time of emitting the lasers and generating timing starting signals, the other path irradiates an object through beam expansion, echo signals are received by an APD array detection module and generate N2 paths of stopping pulses, and a multi-channel high-precision time interval measuring module is combined with starting signals to measure the round-trip flight time difference of N2 paths of lasers of a rectangular detection area. The location attitude measuring sub-system, the master control sub-system and the area array laser radar distance-measuring sub-system of the measuring system are integrated, original three-dimensional information can be obtained in real time, and assembling and verification are eliminated. The laser radar measuring system does not need scanning, three-dimensional imaging can be achieved through a single pulse, the imaging speed is high, measuring precision and working efficiency are high, the size is small, the weight is small, and the small low-altitude light area array laser radar measuring system is suitable for being carried small low-altitude light remote sensing platforms.
