摘要:
Disclosed are remote spatial calibration apparatuses and spatial calibration methods. A first plurality of line-generating lasers is arranged for generating a first set of substantially parallel lines in a first orientation. A second plurality of line-generating lasers is arranged for generating a second set of substantially parallel lines in a second orientation. Both sets of lines are directed to project on an object and the second orientation is substantially perpendicular to the first orientation such that the lines form a matrix of lines. An imaging device is configured for obtaining an image of the object and the matrix of lines formed on the object. The spatial calibration apparatuses may be included in a housing comprising a projection face, an imaging device cavity formed in the projection face, and a plurality of laser cavities formed in the projection face.

A wireless sensor system includes a passive sensor apparatus configured to be embedded within a concrete structure to monitor infiltration of contaminants into the structure. The sensor apparatus includes charging circuitry and a plurality of sensors respectively configured to measure environmental parameters of the structure which include information related to the infiltration of contaminants into the structure. A reader apparatus is communicatively coupled to the sensor apparatus, the reader apparatus being configured to provide power to the charging circuitry during measurements of the environmental parameters by the sensors. The reader apparatus is configured to independently interrogate individual ones of the sensors to obtain information measured by the individual sensors. The reader apparatus is configured to generate an induction field to energize the sensor apparatus. Information measured by the sensor apparatus is transmitted to the reader apparatus via a response signal that is superimposed on a return induction field generated by the sensor apparatus. Methods of monitoring structural integrity of the structure are also provided.

A method of measuring a parameter of a landfill including a cap, without passing wires through the cap, includes burying a sensor apparatus in the landfill prior to closing the landfill with the cap; providing a reader capable of communicating with the sensor apparatus via radio frequency (RF); placing an antenna above the barrier, spaced apart from the sensor apparatus; coupling the antenna to the reader either before or after placing the antenna above the barrier; providing power to the sensor apparatus, via the antenna, by generating a field using the reader; accumulating and storing power in the sensor apparatus; sensing a parameter of the landfill using the sensor apparatus while using power; and transmitting the sensed parameter to the reader via a wireless response signal. A system for measuring a parameter of a landfill is also provided.

Alert information is provided to a user of a device. In response to receiving an alert notification, a current location of the device is determined and converted to a device geographical tile that encompasses the determined current location; alert data received about the alert are processed and stored in an alert database if it is determined that a device tile code of the device geographical tile matches any alert geographical tiles that define the alert; a database query of the alert database is performed to identify alerts having one or more alert geographical tile codes that match the device tile code that have not been presented to a user of the device; and the user of the device is notified via the user interface of the device of the identified alerts and the user is prompted to view the identified one or more alerts via the user interface of the device.

摘要:
An improved door stop for a sliding door to reduce damage to vehicle tires passing over the door stop includes a vertically oriented housing to be embedded in the floor in alignment with the sliding door. A top block supported by a spring is slidable within the housing. A door guide is mounted to the top surface of the top block and extends above it to engage the bottom of the sliding door when the sliding door is moved to a position above the door stop. The top block remains flush with..the top of the housing and the ground surface when the spring is at rest.
