An apparatus including a processor unit configured to provide a first high-definition map, a sensor unit configured for providing sensor data representing an environmental condition in a periphery of the apparatus and a receiver unit configured to receive data representing a second high-definition map. The processor unit is configured to fuse the second high-definition map and the sensor data so as to provide the first high-definition map. The apparatus further includes a transmitter unit configured for transmitting a result of fusing the second high-definition map and the sensor data, and includes a command generator unit configured to generate a command signal representing a vehicle control command for a vehicle carrying the apparatus based on the first high-definition map.

A sensor device for monitoring at least one lifecycle of potatoes, at least from planting seed potatoes to stocking the potatoes includes a body dimensioned and shaped to conform to a potato. The body houses electronics of the sensor device and includes a waterproof layer for protecting the electronics when the sensor device is placed underground with the seed potatoes. The electronics includes a wireless communication circuitry providing the sensor device with radio communication capability, at least one processor, and at least one of the following sensors: a humidity sensor; a temperature sensor; and a carbon dioxide sensor. The at least one processor is configured to store measurement data provided by the at least one sensor, and to cause the wireless communication circuitry to transmit the measurement data to another device.

A checking fixture for a steering knuckle. In use, a workpiece is mounted on the checking fixture, three locating points of the workpiece in the X direction respectively correspond to a supporting pin I, a supporting pin II and a supporting pin III, a locating taper hole limiting the motion of the workpiece in a YZ plane corresponds to the floating pin, and a locating point of the workpiece in the Y direction levelly fit to a supporting surface of a locating pin; after location is completed, the workpiece is tightly clamped by a jacking clamp, a press clamp I and a press clamp II. The checking fixture for the steering knuckle can measure the position accuracy of each hole of the steering knuckle workpiece, and can detect whether the relative height of the flange plane of the workpiece relative to the X-direction locating points is qualified.

Inconspicuous ballistic armor that may be incorporated into or disguised within everyday articles in the environment in which it is deployed. The ballistic armor includes a ballistic shield, an article attached to the front surface of the ballistic shield, and hand/arm straps attached to a rear surface of the ballistic shield. A thin sheet of hardened abrasion-resistant steel may alternatively be affixed to the ballistic shield core and may wrap around the core slightly to allow for attachment of arm straps and hand holds behind the shield. Examples of the article attached to the front surface include a desktop calendar, a whiteboard, corkboard and artwork. The ballistic shield is formed from high strength, lightweight synthetic fiber that can withstand gunfire. The hand/arm straps may be formed from a webbing strap material that is attached, such as by rivets or special fasteners, to the rear surface of the ballistic shield. An autonomous alert and movement tracking system connects the shields to the Internet to allow generation of a map showing locations and movements of shields, and predictive location and movement of the attacker, for use by both the users of the shields and first responders. The shields may also have audio and visual indicators to allow display of alerts.

Technologies are described herein for adaptive polling based upon demand. A data source is polled for data at a first polling frequency. A request is received for a page or other type of resource that includes the data, and the data is provided in response to the request. Subsequently, the data source is polled for the data at a second polling frequency greater than the first polling frequency. Status messages are also received indicating a status of a display of the page. The polling frequency may be adjusted based on the status messages. For example, the polling frequency may be increased if a status message indicates that a user is viewing the data. The polling frequency may be decreased if a status message indicates that the data is not being viewed or that a page or other type of resource for presenting the data has been closed.

Systems and methods for identifying locations and controlling devices are provided. For example, a user may indicate a location by aiming at the location from multiple positions in a physical space. The user may also identify a controllable device to control by aiming at the device. Example systems and methods include determining a first position within a three-dimensional space, receiving a first directional input, and determining a first ray based on the first position and first directional input. Example systems and methods also include determining a second position within the three-dimensional space, receiving a second directional input, and determining a second ray based on the second position and second directional input. Example systems and methods may also include identifying a location within a three-dimensional space based on the first ray and the second ray.
