Abstract: A BLUETOOTH reconnection method is used in a BLUETOOTH connection system that includes a first device and a second device. The method includes that the first device sends a BLUETOOTH Low Energy (BLE) advertising signal to the second device after a BLUETOOTH connection between the first device and the second device is disconnected. If the second device determines that the received BLE advertising signal is a first BLE advertising signal, the second device does not page the first device, and waits to receive a page packet sent by the first device. If the second device determines that the received BLE advertising signal is a second BLE advertising signal, the second device actively pages the first device, and the first device waits to receive a page packet sent by the second device.

Abstract: Structures and techniques provide bond enhancement in microelectronics by trapping contaminants and byproducts during bonding processes, and arresting cracks. Example bonding surfaces are provided with recesses, sinks, traps, or cavities to capture small particles and gaseous byproducts of bonding that would otherwise create detrimental voids between microscale surfaces being joined, and to arrest cracks. Such random voids would compromise bond integrity and electrical conductivity of interconnects being bonded. In example systems, a predesigned recess space or predesigned pattern of recesses placed in the bonding interface captures particles and gases, reducing the formation of random voids, thereby improving and protecting the bond as it forms. The recess space or pattern of recesses may be placed where particles collect on the bonding surface, through example methods of determining where mobilized particles move during bond wave propagation.
