A path planner and a method for determining a path for a vehicle comprises defining a starting point for the vehicle. A termination point is defined. An obstacle detector detects one or more obstacles in a work area between the starting point and the termination point. A boundary zone is defined about each corresponding obstacle. Candidate paths are identified between the starting point and the termination point. Each candidate path only intersects each boundary zone once for each corresponding obstacle. An economic cost is estimated for traversing each candidate path or a portion thereof between the starting point and the termination point. A preferential path is selected from the identified candidate paths based on the preferential path being associated with a lowest estimated economic cost.

A method and system for displaying information related to a plurality of resources in a network environment. The system uses web technology to receive and store information related to back-end resources and to provide a framework by which client computer systems can manage the plurality of back-end resources in a uniform manner. In accordance with one method, a request is received to display object information from different network resources. In response, attribute and task information is retrieved from the appropriate different network resources and this information is displayed. A graphical user interface (GUI) displays information related to network resource objects. The GUI includes a console displaying a tool zone and a work zone. A module is displayed in the work zone having an object zone displaying a list of objects and a task zone displaying a list of tasks.

Radio frequency identification tags are spaced apart from one another in or around a work area for the vehicle. Each of the tags has a corresponding unique identifier. A path planning module establishes a path comprising a path segment between at least two of the radio frequency identification tags. The path segment comprises at least one of a distance between the tags, an angular heading between the tags, and unique identifiers corresponding to the tags. A data processor determines an estimated position of the vehicle based on at least one of odometer data and accelerometer data. A vehicle controller navigates between at least two of the radio frequency identification tags based on the estimated position, the distance and the angular heading. A reader reads the tag identifiers of each tag to track the progress of the vehicle to facilitate execution of or retrieval of any next path segment of the vehicle along the established path.

A method for treating stenosis in a spine comprises percutaneously accessing the epidural space in a stenotic region of interest, compressing the thecal sac in the region of interest to form a safety zonem, inserting a tissue removal tool into tissue in the working zone, using the tool to percutaneously reduce the stenosis; and utilizing imaging to visualize the position of the tool during at least a part of the reduction step. A tissue excision system for performing percutaneous surgery, comprises a cannula comprising a tissue-penetrating member having a distal end defining an aperture on one side thereof, an occluding member slidably received on or in the cannula and closing the aperture when the occluding member is adjacent the cannula distal end, means for engaging adjacent tissue via the aperture, and cutting means for resecting a section of the engaged tissue.

An autonomous robot and a positioning method thereof are disclosed. The autonomous robot includes an environment information detection device, a map construction module, a setting module, a path planning module, and a driving module. The environment information detection device is for detecting environment information about an environment where the autonomous robot is situated. An environment map is constructed based on the environment information detected by the environment information detection device. The setting module is used for setting a working boundary on the environment map. The path planning module is for planning a moving path in a working zone and is electrically connected to the setting module. The driving module for driving the autonomous robot to move along the moving path is electrically connected to the path planning module.

A mobile work zone protection device includes a front carrier, a barrier beam assembly, and a rear carrier. In one embodiment, the barrier beam assembly includes two sets of telescoping beam structures. Each of these structures can rotate from one side of the device to the other, and thus can be deployed to create a safe work zone for roadway workers on either side of the device. The structure can also be left in the transit position to provide an enclosed safe work zone.

A novel dynamic work zone safety system and method of traffic control for a construction work zone are provided herein. The system includes at least two traffic signalling device which are positioned along a roadside immediately upstream of a point where traffic is diverted to a single lane. The traffic signalling devices selectively flash a suitable warning, e.g., "DO NOT PASS" or "MERGE LEFT" or "MERGE RIGHT", thereby to provide at least two "NO PASSING" or "MERGE LEFT" or "MERGE RIGHT" zones which is defined by the distance between the traffic signalling devices and the end of the work or construction zone. The "NO PASSING" or "MERGE LEFT" or "MERGE RIGHT" zones traffic signalling device and the end of the work or construction zone may thus be expanded or contracted. A plurality of spaced-apart sensors is disposed along the roadway both downstream of, and upstream of, the traffic signalling devices to detect and determine the length of traffic queues upstream of the traffic signalling devices, and provides signals which are representative of the length of the traffic queues. The processor receives the traffic queue signals and generates activation signals when the traffic queue reaches a predetermined length. It also generates a deactivation signal when the traffic queue is less than the predetermined length. This dynamically increases or decreases the "NO PASSING" or "MERGE LEFT" or "MERGE RIGHT" zone.

The invention provides a method for manufacturing a stainless steel or compound steel non-stick pan and belongs to the technical field of non-stick pan manufacturing technique. The method solves the technical problems that the non-stick performance of a non-stick pan in the prior art is poorer and pollution can be easily caused. The method comprises the following steps that a, surface pattern treatment: concave-convex lines with preset patterns are formed in a preset zone on the surface of a stainless steel plate through a chemical etching, graving or rolling depression method; b, drawing forming: the stainless steel plate body is drawn to form a pan body, and the preset zone is positioned in the working zone of a formed pan body; c, spraying of non-stick coating: non-stick coating is sprayed to the preset zone on the inner surface of the pan body, so that the non-stick coating is coated on the preset zone on the inner surface of the pan body; d, polishing: the preset zone on the inner surface of the pan body is subjected to mechanical polishing, the non-stick coating on the convex surfaces of the concave convex lines is removed, and the non-stick coating on the concave surfaces of the concave convex lines is retained. The method for manufacturing the stainless steel or compound steel non-stick pan has the advantages of durability and good non-stick property.
