Electronic drill guide

One embodiment of an alignment apparatus for aligning an object, such as a tool or other implement, perpendicular with respect to a horizontal or a vertical target surface, comprises a three-axis accelerometer and at least two forward-facing distance sensors and a projection display comprising four addressable laser projectors. The accelerometer and distance sensor outputs are mapped to a predefined graphic symbol representing the orientation of the tool relative to the target surface, in particular when the tool is perpendicular to the target surface. The projection display projects the predefined symbol onto the target surface where it may be easily viewed by the tool operator allowing the operator to make any necessary corrections to the tool position.

Object detector, object detecting method and robot

An object detector, an object detecting method and a robot can reduce diction errors of detecting wrong objects without increasing the volume of the computational operation to be performed to detect the right object. A face detector 101 comprises a face detecting section 110 that operates like a conventional face detecting section and is adapted to roughly select face candidates from an input image by template matching and detect face candidates by means of a support vector machine for face recognition, a non-face judging section 120 that detects non-face candidates that are judged to be non-faces and removes them from the face candidates selected by the face detecting section 110 and a skin tracker section 114 for tracking a face region after the non-face judgment. When the assumed distance between the face detector and the face as computed from the input image and the measured distance as measured by a distance sensor show a large difference, when the color variance of the face candidate is small, when the occupancy ratio of the skin color region is large and when the change in the size of the face region is large after the elapse of a predetermined time, the non-face judging section 120 judges such face candidates as non-faces and removes them from the face candidates.

Product integrity systems and associated methods

The invention provides a smart sensor in the form of an adhesive bandage. The sensor may be used in many applications such as within sports, the shipping industry and medical and health industries. The sensor sticks to people and objects and wirelessly communicates with remote receivers. Internal detectors sense conditions associated with movement and / or the environment of the sensor. In one example, an accelerometer detects impact and drop distance of a package in transit; the sensor is either within a label or attached to a product within the package. The sensor may also prevent theft and assist in tracking package disposition so as to reduce lost packages. The sensors of the invention may also be used in fitness and health, such as to monitor body functions of heart rate and respiration; these sensors also may initiate immediate wireless warnings for improper functions so that persons may obtain immediate assistance. Sensors of the invention are also useful for sports media broadcasts; multiple sensors may attach to athletes so that wireless performance data is made available, in near real time, to audiences and media observers. Data from sensors of the invention may also change the computer gaming community; that is, certain sensors tracking real performance data may relay information used within gaming so as to govern computer gaming motions. Typically, sensors of the invention communicate by an RF transmitter or transceiver. Groups of sensors may be combined within a common canister that imparts date and time information and “power on” when dispensed.

Controlling unmanned aerial vehicles to avoid obstacle collision

A method, device, framework, and system provide the ability to control an unmanned aerial vehicle (UAV) to avoid obstacle collision. Range data of a real-world scene is acquired using range sensors (that provide depth data to visible objects). The range data is combined into an egospace representation (consisting of pixels in egospace). An apparent size of each of the visible objects is expanded based on a dimension of the UAV. An assigned destination in the real world scene based on world space is received and transformed into egospace coordinates in egospace. A trackable path from the UAV to the assigned destination through egospace that avoids collision with the visible objects (based on the expanded apparent sizes of each of the visible objects) is generated. Inputs that control the UAV to follow the trackable path are identified.

Method for a changing safety signaling system

The present invention provides a method for a changing safety signaling system. The safety signaling system can change as a result of changing driving conditions that stem from changes in the weather or changes in vehicle velocity. As a vehicle brakes, coasts, turns, or accelerates, front-facing, side-facing, top-facing, and / or rear facing indicators can communicate vehicular acceleration, coasting, and braking to a pedestrian or other vehicles. A distance sensor can be used to trigger a signal to alert a second vehicle that the first vehicle is braking hard and slowing fast or can be used to warn the operator of the first car that a collision may be imminent and can be used to warn the operator of a second car that measures can be taken to avoid a collision or minimize damage from a collision.

A Micro Inertial Measurement Unit (IMU) which is based on MEMS accelerometers and gyro sensors is developed for real-time recognition of human hand motions, especially as used in the context of writing on a surface. Motion is recorded by a rate gyro and an accellerometer and communicated to a Bluetooth module, possibly to a computer which may be 20 to 30 feet or more from the sensor. The motion information generated and communicated is combined with appropriate filtering and transformation algorithms to facilitate a complete Digital Writing System that can be used to record handwriting on any surface, or on no surface at all. The overall size of an IMU can be less than 26 mm×20 mm×20 mm, and may include micro sensors, a processor, and wireless interface components. The Kalman filtering algorithm is preferably used to filter the noise of sensors to allow successful transformance of hand motions into recognizable and recordable English characters.
