Abstract: A symmetric cryptography for encrypting and decrypting information is provided, that can be implemented efficiently in hardware or in software. The symmetric cryptography uses a key generator, so that the cryptography is not dependent on a single, static cryptography key. The key generator is a value or collection of values from which the key is generated. In some embodiments, the key generator substantially increases the computational complexity of differential cryptanalysis and other cryptographic attacks because it has more entropy than the key(s). In an embodiment, the key generator is updated with one-way functions exhibiting the avalanche effect, which generates an unpredictable sequence of keys used during the encryption or decryption process. In an embodiment, a dynamic key is derived from a key generator with a one-way function. In an embodiment, a block cipher uses a different dynamic key to encrypt each block of plaintext, where each key is derived from a different key generator.

Abstract: According to one or more examples, a system includes an observer vehicle, and a vehicle in a predetermined vicinity of the observer vehicle. The observer vehicle detects an operating condition of the vehicle using one or more perception devices.

The observer vehicle identifies a communication identifier of the vehicle. The observer vehicle sends the message to be received by the vehicle using the communication identifier via a vehicle to everything (V2X) communication module.

Abstract: To enhance a mono-output-only controller such as a mobile OS to support selective mono/stereo/mixed output, a stereo controller is instantiated in communication with the mono controller. The stereo controller coordinates stereo output, but calls and adapts functions already present in the mono controller for creating surface and image buffers, rendering, compositing, and/or merging. For content designated for 2D display, left and right surfaces are rendered from a mono perspective; for content designated for 3D display, left and right surfaces are rendered from left and right stereo perspectives, respectively. Some, all, or none of available content may be delivered to a stereo display in 3D, with a remainder delivered in 2D, and with comparable content still delivered in 2D to the mono display. The stereo controller is an add-on; the mono controller need not be replaced, removed, deactivated, or modified, facilitating transparency and backward compatibility.

Abstract: To manage a plurality of parking spaces, one or more images are acquired, with each parking space appearing in at least one image. Periodically acquired images of occupancy and identity are used in directing a customer to a parked vehicle. Periodically acquired mages of just occupancy are used in controlling respective environmental aspects, such as illumination and ventilation, of the parking spaces. For these purposes, the images are classified automatically as “vacant” or “occupied”, and are displayed along with their classifications so that the classifications can be corrected manually.
