Abstract: Example embodiments described herein relate to a modular telematics control unit (TCU) with directional Bluetooth Low Energy (BLE) and techniques for using the modular TCU with directional BLE. A modular TCU may include a housing configured to couple to a vehicle and a set of Bluetooth Low Energy (BLE) radios. Each BLE radio is coupled to a corresponding BLE antenna configured for omnidirectional operation. The set of BLE radios and BLE antennas are located within the housing. The modular TCU also includes a heat sink located within the housing and positioned proximate the BLE antennas such that the heat sink limits operation for each BLE antenna to a particular direction extending away from the housing. In some instances, a vehicle computing system may use BLE to detect a device and perform operations based on the location of the device relative to the vehicle.

Abstract: Example embodiments described herein relate to enhancing vehicle connectivity using a modular telematics control unit (TCU) that includes antennas, radios, and other components positioned internally within a housing configured to couple to a vehicle. The TCU may include a first cellular radio configured to establish a wireless connection with a first cellular network using a first cellular transmission antenna and a first cellular reception antenna and a second cellular radio configured to establish a wireless connection with a second cellular network using a second cellular transmission antenna and a second cellular reception antenna. The TCU also includes a Wi-Fi radio coupled to a set of antennas and configured to provide a Wi-Fi network for passenger devices located inside the vehicle when the housing is coupled to the vehicle and one or more Bluetooth low energy (BLE) radios coupled to an antenna.

Abstract: A computer-implemented method for bytecode class verification includes: encountering a class requiring verification of its bytecode during a run of an application; determining whether class relationship data for the class exists in a shared classes cache; in response to a determination that the class relationship data for the class does not exist in the shared classes cache: performing a linear bytecode walk of the bytecode to identify relationship data for the class and verify that the bytecode is well-formed; and storing the identified relationship data as the class relationship data for the class in the shared classes cache; in response to a determination that the class relationship data for the class does exist in the shared classes cache: retrieving the class relationship data for the class from the shared classes cache; and processing the class relationship data.

Abstract: During verification of a bytecode, when a second class remains to be loaded for verification in an MRE, a verifier in the MRE is prevented from loading the second class, where the bytecode includes a relationship between a first class and the second class. The relationship is recorded and the verifier is caused to omit a loading operation on the second class. An execution is started of an application encoded in the bytecode. The second class is caused to be loaded and verified prior to a use of the second class during the execution.
