The method further includes making a second determination that the upward angular velocity exceeds a threshold upward angular velocity and, responsive to the first and second determinations, causing the wearable computing device to move the menu such that the menu becomes more visible in the view region.

Abstract: Devices and methods are provided for measuring, on a digital microfluidic platform, electrical signals associated with the impedance of adherent cells. In one embodiment, a sub-droplet of cell culture media containing adherent cells is passively dispensed at a pre-selected electrode location where a local hydrophilic surface region is provided, and adherent cells are attached to the local hydrophilic surface region. The cell culture media sub-droplet is replaced with a sub-droplet of a low-conductivity medium in a passive dispensing step, retaining the attached adherent cells. An AC voltage with a suitable frequency is applied between electrodes of the device and a signal associated with the impedance of the adherent cells is obtained. One of the electrodes to which the AC voltage is applied may be a dedicated sensing electrode. The local thickness of a dielectric layer coating the pre-selected electrode may be reduced to increase the detection sensitivity of the device.

Abstract: Exemplary methods and system relate to creating a device group snapshot which allows the states of multiple devices to be stored and restored. A hub device may create a device group snapshot for a group of devices by detecting a change in context, selecting one or more devices from the device group to include in the device group snapshot, determining a state for each selected device, and storing a data record corresponding to the device group snapshot. The stored data record for the device group snapshot comprises an indication of the change context and a state record for each selected device. Each state record may include an identifier of the selected device, the determined state of the selected device, and an application state corresponding to the applications on the selected device.
