Abstract: A multi-antenna structure may include a monopole and a first antenna array connected to the monopole at a first location via a first mounting apparatus and including a first cellular antenna and a first radio unit. The structure may also include a second antenna array connected to the monopole at a second location via a second mounting apparatus, with a second cellular antenna and a second radio unit. The structure may include a first set of fronds arranged about an outer surface of the monopole, forming a first respective angle with the monopole and configured to obscure the first antenna array from view. The structure may include a second set of fronds arranged about the outer surface of the monopole, each of the second set of fronds forming second respective angle with the monopole. The second set of fronds may be configured to obscure the second antenna array from view.

Abstract: A display system for use in a vehicle, the display system including first and second controllers in communication with each other and a display mounted in the vehicle. The display is communicatively coupled to the second controller and has a display area. The first controller executes the steps of incorporating a pattern in a set of data thereby producing a dataset; and communicating the dataset to the second controller. The second controller executes the steps of receiving the dataset from the first controller; rendering a graphic from the dataset; and making the rendered graphic available to the display for display in the display area. The first controller then additionally executes the steps of reading the rendered graphic; and evaluating the rendered graphic to see if the pattern has been correctly processed by the second controller.

Abstract: A clamp that is capable of attaching to a battery post and also to a female receptacle terminal. The clamp includes a post-grasping portion that is capable of attaching to the battery post. The clamp also includes a male plug feature that is configured to fit into a female receptacle terminal.

Abstract: A security system is provided for a cargo container having a door. An electronic control unit is provided for monitoring the locked status of the door. The electronic control unit is operably communicable with a remote computer terminal. A first software control program is located within the electronic control unit to monitor the locked status of the door. A second software control program is located within the remote computer terminal and is capable of retrieving activity and functions from the first software control program. A protocol is provided to facilitate communication between the electronic control unit and the remote computer terminal.

Abstract: An electronic battery tester, comprising first and second connectors configured to electrically couple to terminals of the battery, a microprocessor configured to test the battery using the first and second connectors, a memory containing a set of locked instructions for the microprocessor, an input configured to receive a software unlocking key, and the microprocessor configured to execute the set of locked instructions in response to the software unlocking key corresponding a predetermined software unlocking key.

Abstract: An electronic battery tester connectable to a battery through any one of multiple cables. The tester includes an input that can couple to any one of the multiple cables. Also included is a memory that contains multiple calibration values, each calibration value corresponds to a different one of the multiple cables. Test circuitry, which is coupled to the input and to the memory, detects which one of the multiple cables is coupled to the input, and tests the battery as a function of one of the multiple calibration values that corresponds to the detected one of the multiple cables.
