Abstract: An integrated circuit structure includes a device layer including a first set of devices and a second set of devices. An interconnect layer is above the device layer, where the interconnect layer includes one or more conductive interconnect features within dielectric material. In an example, a first ring structure including conductive material extends within the interconnect layer, and a second ring structure including conductive material extends within the interconnect layer. In an example, the second ring structure is non-overlapping with the first ring structure. In an example, the first ring structure is above the first set of devices of the device layer, and the second ring structure is above the second set of devices of the device layer.

Abstract: A security device paired with a user's cell phone is operable by either a trigger or an accelerometer. The device includes visual and audio alarms, a prerecorded message and an audio recording of the ambient noise. Depression of the trigger will spray mace onto an attacker, activate the alarms and alternately send the message and recording to 9-1-1 or other security monitor. Alternatively, the accelerometer will so activate the device. The alarms and transmissions are synchronized so as to not interfere one with the other. Direct communication with 9-1-1 via the Bluetooth®/cell phone interface is immediately established either by a push-to-talk button or at the termination of a predetermined alarm and message transmission period.
