An electrically conductive adhesive layer includes an adhesive material; a plurality of electrically conductive first particles dispersed in the adhesive material and having a first shape; and a plurality of electrically conductive second particles dispersed in the adhesive material and having a second shape different from the first shape. A ratio of a total weight of the first particles to a total weight of the second particles is in a range from about 2 to about 10. The adhesive layer has an average thickness in a range from about 5 micrometers to about 35 micrometers. An electrical conductance of the adhesive layer in a thickness, but not in an in-plane, direction is at least 5% greater than a comparative adhesive layer having the same construction except that it does not include the second particles.

The disclosed embodiments provide computer-implemented systems and methods for batch picking optimization. They system may include one or more memory devices storing instructions and one or more processors configured to execute the instructions to receive an order comprising one or more items for picking. Additionally, the system may calculate one or more high density areas in a fulfillment center by calculating distances between a first item in the one or more items and at least one other item in the one or more items using a search algorithm. Additionally, the system may calculate nearest neighboring items for the one or more items and generate a high density area by choosing a plurality of the nearest neighboring items.

Warehouse batch product picking optimization using high density areas to minimize travel distance

A method and apparatus for performing time synchronization and an OFDMA receiver thereof are provided. The method preferably includes performing a differential phase correlation in a frequency domain based on one received sequence and one reference preamble and detecting an integer frequency offset based on a result of the differential phase correlation. The method and apparatus advantageously enable the use of one OFDM symbol to estimate ICFO and the use of a simple method to facilitate ICFO detection. Moreover, the performance of the integer frequency offset estimation becomes more robust in high noise and time-variant fading channels, with reduced hardware complexity.

Method and apparatus for integer frequency offset estimation in wireless communication system

A method and apparatus for time synchronization and an OFDMA receiver thereof are provided. A preamble timing is obtained by a two-stage correlation in a time domain between a sequence of a received symbol and a reference preamble. The two-stage correlation is further simplified to perform a conjugate multiplication between a one-stage correlation and its correspondingly delayed result. A preamble boundary is adaptively determined by a peak value based on a result of the two-stage correlation. In this way, the time synchronization is achieved with a robust performance in a low SNR, high frequency offset or large delay spread fading channel.
