摘要:
A cargo-sensing unit including: an image sensor; at least one processor; and a memory having stored thereon computer program code that, when executed by the processor, controls the at least one processor to: instruct the image sensor to capture an image of a cargo space within a cargo container; compare the captured image to a baseline image of an empty cargo container; and determine, based on the comparison between the captured image and the baseline image, a cargo space utilization estimate.
摘要:
A multi-relay including a first relay switch operable over a first current range; a second relay switch operable over a second current range; and a current sensor configured to: detect an input current; in response to the input current being within the first current range, activate the first relay switch; and in response to the input current being within the second current range, activate the second relay switch.
摘要:
A diagnostic port connector for a vehicle that includes a locking mechanism is disclosed. The system can comprise a connector body, such as a male OBD-II connector. The connector can include a plurality of connector pins, with the pins capable of passing signals and messages from the vehicle's on board diagnostic system to a device in electrical communication with the connector. The connector can also include a connection retention component. The connection retention component can be configured to maintain a connection between male connectors and female connection ports by interfering with a protruding portion of the female connection port.
摘要:
A system for renting vehicles is disclosed. The system can comprise a vehicle access communicator (“VAC”) capable of interfacing with one or more functions of a rental vehicle and a user provided portable electronic device. The VAC can control various functions of the vehicle including, but not limited to, the door locks and/or enabling/disabling the vehicle. The VAC can also monitor various functions of the vehicle including, but not limited to, the fuel level and/or the odometer readings. The VAC can connect to the portable electronic device using a suitable connection method to access additional functionality such as, for example and not limitation, locations services, cellular, and/or internet access. The VAC and the portable electronic device can be used to provide a rental system with reduced infrastructure and operating costs. The system can enable the use of “Green Zones” to provide permanent or temporary vehicle rental areas.

Implementations for a system to receive a message indicating that an ambient light level measured by an ambient light sensor within a container exceeds a first threshold value or falls below a second threshold value; in response to the message indicating that the ambient light level exceeds the first threshold value, activate a cargo sensor; and in response to the message indicating that the ambient light level falls below the second threshold value, de-activate the cargo sensor.

摘要:
A robust wireless communications system operable to provide communications for mobile wireless devices. The wireless communications system generally includes a management computing system, wireless infrastructure, and mobile wireless devices. The wireless infrastructure includes wireless infrastructure devices having processing and storage capability. Similarly, the mobile wireless devices include processing and storage capability. Communication links between the management computing system and wireless infrastructure, and wireless infrastructure and mobile wireless devices are utilized to downlink and uplink data. In operation, data generated at the management computing system may be downloaded to the wireless infrastructure and mobile wireless devices sequentially without active simultaneous communication links. Similarly, data generated at the mobile wireless devices may be uploaded to the wireless infrastructure and management computing system without active simultaneous communication links. Because the wireless infrastructure and mobile wireless devices are intelligent, decisions may be made independent of a communication link existing with the management computing system.
摘要:
The disclosed technology relates to systems and methods for weighing transportation vehicles and cargo and determining their load state. The disclosed technology can include a sensor controller configured to received one or more sensor readings from weight sensors on a cargo vehicle. The sensor controller can determine an inclination and/or deflection of the cargo vehicle and modify the sensor readings based on the inclination and/or deflection. The sensor controller can calculate a weight of cargo carried by the cargo vehicle based on the modified sensor readings.
摘要:
A power source and power management system including: a controller configured to transmit tracking information of the power source and power management system; an energy harvesting power source; a non-degrading rechargeable power source electrically connected to the energy harvesting power source and configured to be recharged by energy generated by the energy harvesting power source; and a power manager configured to control switching of a system power source between the energy harvesting power source and the non-degrading rechargeable power source based on a power state of the energy harvesting power source and a power state of the non-degrading rechargeable power source.
