Proximity sensing is the ability of a robot to tell when it is near an object, or when something is near it. This sense keeps a robot from running into things. It can also be used to measure the distance from a robot to some object. The simplest proximity sensors do not measure distance.
Method and apparatus for integrating manual input
InactiveUS6888536B2Simple methodEasy to learnInput/output for user-computer interactionImage analysisLow noiseBiomechanics
Apparatus and methods are disclosed for simultaneously tracking multiple finger and palm contacts as hands approach, touch, and slide across a proximity-sensing. compliant, and flexible multi-touch surface. The surface consists of compressible cushion, dielectric, electrode, and circuitry layers. A simple proximity transduction circuit is placed under each electrode to maximize signal-to-noise ratio and to reduce wiring complexity. Such distributed transduction circuitry is economical for large surfaces when implemented with thin-film transistor techniques. Scanning and signal offset removal on an electrode array produces low-noise proximity images. Segmentation processing of each proximity image constructs a group of electrodes corresponding to each distinguishable contact and extracts shape, position and surface proximity features for each group. Groups in successive images which correspond to the same hand contact are linked by a persistent path tracker which also detects individual contact touchdown and liftoff. Combinatorial optimization modules associate each contact's path with a particular fingertip, thumb, or palm of either hand on the basis of biomechanical constraints and contact features. Classification of intuitive hand configurations and motions enables unprecedented integration of typing, resting, pointing, scrolling, 3D manipulation, and handwriting into a versatile, ergonomic computer input device.

A robotic catheter control system includes a proximity sensing function configured to generate a proximity signal that is indicative of the proximity of the medical device such as an electrode catheter to a nearest anatomic structure such as a cardiac wall. The control system includes logic that monitors the proximity signal during guided movement of the catheter to ensure that unintended contact with body tissue is detected and avoided. The logic includes a means for defining a plurality of proximity zones, such as a GREEN, YELLOW and RED designated zones, each having associated therewith a respective proximity (distance) criterion, with the RED zone being the nearest to the body tissue and the YELLOW zone being the next nearest to the body tissue. When the logic detects entry of the catheter into the RED zone, the logic terminates the operating power to the actuation units of the control system, to thereby stop movement of the catheter entirely. When the logic detects entry of the catheter into the YELLOW zone, the logic automatically reduces a pre-planned navigation speed of the catheter.

Device with proximity detection capability

The electrical equivalent of a relatively large area proximity detection capability is provided in a space limited electronic device (20, 30) with many individual input electrodes (24, 34, 44) by dynamically coupling parallel groups of the individual electrodes (24, 34, 44) and applying a proximity and / or contact test thereto. The parallel grouped electrodes act like a single large electrode and permit proximity detection at greater distances and with greater sensitivity. A multiplexer (74) automatically couples individual input electrodes (23, 24, 44) and then parallel grouped electrodes to the proximity (or contact) sensor(s) (46, 66), so that they are scanned and sensed individually and collectively in a time less than human reaction time, whereby the proximity sense function appears as if provided by a separate large area electrode. Proximity spatial detection accuracy is increased by using some of the electrodes (24, 34, 44) as driven shields to remove positional ambiguity.

Electronic device having a proximity detector
A smoke detection device for use in a portable device such as a mobile terminal. The smoke detection device comprises a light emitter and a light detector disposed on different locations on the portable device so that when smoke or an intruding object is presence in the light path of the light emitter outside the device housing, it causes the light emitted by the light emitter to be scattered or reflected. When the light detector senses the scattered or reflected light, it can cause an alarm signal to be produced by the portable device. The emitted light can be in the infrared region so that the detection is independent of the ambient light. Alternatively, the light emitter is operated in a pulsed mode. Additional light emitter and light detectors can be disposed on the portable device for proximity sensing in addition to smoke detection.

Proximity sensing based on antenna impedance variation
InactiveUS7113087B1Simple and economical mannerReduce and avoid needEnergy efficient ICTDigital data processing detailsElectricityAntenna impedance
Proximity of a user body part can be detected by measuring the effects such proximity has on antenna impedance mismatches. The amount of mismatch affects the amount of RF signal energy reflected back into a transmission line connecting the antenna to a RF signal source. A directional coupler has a main line electrically connected to the transmission line, as well as a coupled line. The directional coupler produces a signal on its coupled line in relation to the magnitude of reflected energy on the transmission line; the amount of reflected energy varies in response to how well the antenna impedance matches the transmission line impedance. A signal detector is electrically connected to the coupled line, and responds to signals produced in the coupled line by the main line. The signal detector output is then used to determine whether a body part is in proximity. Other aspects the invention include an adaptive algorithm to adjust a threshold for proximity determination.
