Mobile robotic system with web server and digital radio links

The invention is a computerized mobile robot with an onboard internet web server, and a capability of establishing a first connection to a remote web browser on the internet for robotic control purposes, and a capability of establishing a second short range bi-directional digital radio connection to one or more nearby computerized digital radio equipped devices external to the robot. The short-range bi-directional digital radio connection will typically have a maximum range of about 300 feet. In a preferred embodiment, this short-range wireless digital connection will use the 2.4 gHz band and digital protocols following the IEEE 802.11, 802.15, or other digital communications protocol. By employing the proper set of external short-range digital radio devices capable of interfacing with the robot (such as sensors, mechanical actuators, appliances, and the like), a remote user on the internet may direct the robot to move within range of the external devices, discover their functionality, and send and receive commands and data to the external devices through the CGI interface on the robot's onboard web server.

System and method for selection of materialized views

A method for selecting and recommending materialized views is described, in which a set of workload queries is classified in terms of a number of structural features that includes the structure of the join operations in the query (“full query join graph”), the structure of a specific subset of the join operations (“anchor join graph”), and other characteristics such as the measures, selection predicates, and grouping conditions employed in the query. These features are used to implement a two-level partitioned search for the recommended materialized views.

Sensor-equipped rolling bearing assembly

A sensor-equipped rolling bearing assembly includes: a cylindrical fixed bearing ring fixed to a vehicle body; a rotary bearing ring rotatably inserted through the fixed bearing ring and having a wheel-mounting portion on an outboard side thereof; and plural rows of rolling elements rollably interposed between these bearing rings. The bearing assembly is provided with a case member having plural displacement sensors which are circumferentially arranged at predetermined space intervals and which detect gaps between themselves and an outside surface of an inboard end of the rotary bearing ring. The case member is mounted to the inboard end of the fixed bearing ring.

Calibration method for underwater binocular vision measurement system

The invention belongs to the technical field of underwater detection and measurement, aiming at solving the problem that the existing underwater binocular vision measurement system does not have generality and cannot be applied to the occasions with high precision, so that all underwater detection and measurement requirements can not be met. For this purpose, the invention provides a calibration method for an underwater binocular vision measurement system, which calibrates a binocular camera in air to obtain an internal parameter matrix and distortion parameters. The image of checkerboard gridis taken by binocular camera under water and distortion correction is carried out. Corner points of checkerboard grid are detected and position coordinates of corner points are measured by refractionrelation under water. According to the relative positional relationship between the corners of the checkerboard, the optimization objective is designed, and the calibration of the underwater binocular vision measurement system is completed by multi-objective optimization. The invention can improve the measurement accuracy of the underwater binocular vision measurement system, enable it to meet the requirements of the occasions with higher accuracy, improve the generality of the underwater binocular vision measurement system, and meet all underwater detection and measurement requirements.

Movable type safety inspection device based on X-ray

The invention provides a movable type safety inspection device based on X-ray. The movable type safety inspection device based on the X-ray comprises a ray launcher and a ray receiving device. The ray launcher and the ray receiving device are fixedly arranged at two ends of a source detecting frame respectively. A sliding block is fixedly arranged at the bottom end of the source detecting frame. The sliding block is matched with a guide rail which is fixedly arranged at the upper end of a base to slide. The source detecting frame is driven by a transmission mechanism and conducts reciprocating motion along the guide rail through the sliding block. The transmission mechanism is fixedly arranged on the base. The source detecting frame which is provided with the ray launcher and the ray receiving device conducts wholly and transversely reciprocating motion in hidden space which is formed by an inner frame and an outer frame to achieve the detection to people and objects. The safety inspection device is driven through the transmission mechanism, reciprocating type moving scanning imaging detection is achieved, the result of the detection is improved, and the device is high in invisibility and strong in operability.

Apparatus and method for detecting transparent substances

PCT No. PCT / JP97 / 00461 Sec. 371 Date Oct. 21, 1997 Sec. 102(e) Date Oct. 21, 1997 PCT Filed Feb. 19, 1997 PCT Pub. No. WO97 / 31384 PCT Pub. Date Aug. 28, 1997A semiconductor light-emitting device which emits first light of a wavelength absorbed by a substance containing an OH group is sent toward a detection object. A semiconductor light-emitting device emits second visible light toward the detection object. A photoreceptor receives light from the detection object and acquires first and second received light-quantities derived from the respective ones of the first and second light. A processing system corrects the first photoreceiving quantity on the basis of the second photoreceiving quantity. The processing system determines the color of the detection object by the second photoreceiving quantity, and corrects the first photoreceiving quantity on the basis of this determination result. Further, it compares the corrected first photoreceiving quantity with a prescribed threshold value, detects whether or not water, which is the subject containing the OH group, is contained in the detection object, and outputs the same as an output signal.
