Abstract: For a mobile device having a main battery and a backup power source, a method is provided for wirelessly charging the backup power source using a reader when the main battery of the mobile device is fully depleted and unable to provide enough power for an RF transaction. The reader detects the mobile device cannot perform the RF transaction. In response, the reader generates an RF field that provides charge for the backup power source of the mobile device. After charging is complete, the mobile device performs the RF transaction using the charged backup power source. In one embodiment the mobile device is a mobile phone being used as a digital key and the reader is implemented in a smart door handle of an automobile that is unlocked by the RF transaction.

Abstract: A method of forming an assembly is provided. The method includes attaching a packaged semiconductor device to a substrate. An isolation structure is formed and located between the packaged semiconductor device and the substrate. An underfill material is dispensed between the packaged semiconductor device and the substrate. The isolation structure prevents the underfill material from contacting a first conductive connection formed between the packaged semiconductor device and the substrate.

Abstract: A method of manufacturing a semiconductor device is provided. The method includes attaching a first semiconductor die to a first die pad of a first leadframe and attaching a second semiconductor die to a second die pad of a second leadframe. The first leadframe is attached to the second leadframe by way of a non-conductive adhesive. A first plurality of leads of the first leadframe are interleaved with leads of a second plurality of leads of the second leadframe. The first and second semiconductor die and portions of the first and second leadframes are encapsulated with an encapsulant.

Abstract: A security platform includes a security tag having a wireless communication circuitry configured to receive a user identification (ID) from an ID tag. After receiving the user ID, the security tag tracks the distance the security tag moves away from a predetermined point. The security tag then compares the determined distance to a predetermined distance threshold to determine whether the security tag is within a range. In response to the determined distance being greater than the predetermined distance threshold, the security tag determines that the security tag is outside of the range and activates an alarm. The alarm of the security tag continues to be active until a second user ID having appropriate access rights is received.

Abstract: A computing system divides an initial seed network into a plurality of blocks to form a network search space that includes candidate neural architectures. For each block in the plurality of blocks, sample-based search spaces are defined. Each sample-based search space includes candidate block configurations. The candidate block configurations are determined by determining candidate block configurations that minimize a block-wise knowledge distillation loss. A first set of block configurations that are Pareto optimal block configurations are determined from the candidate block configurations in the sample-based search spaces. Sub-super-net search spaces for each block configuration in the first set of block configurations are determined. Using input training data, each of the sub-super-net search spaces are trained to generate a trained candidate models. An optimized neural architecture is determined by determining a first trained candidate model of the trained candidate models that minimizes a knowledge distillation loss of the trained candidate models.

Abstract: A first device operates to utilize RF signaling for both communication signaling and radar sensing. The first device transmits a first RF signal representing a first OFDM symbol at time index k−1 and transmits a second RF signal representing a second OFDM symbol at time index k. The first and second OFDM symbols represent communication data for receipt by at least a second device, and have cyclic prefixes of a length less than a channel length used for radar sensing by the JCAS device. A third RF signal that is a scattered representation of the second RF signal is received at the first device, and a compensation matrix determined from at least both the first and second OFDM symbols is used to compensate for ISI present in the third RF signal. From this compensated result a set pf radar channel coefficients representing the local environment are determined.
