Abstract: Provided herein are methods and related systems for controlling droplet spreading on a surface, including droplets in which a biological component is suspended. A biological solution is provided as a droplet to a surface. Interference fringes generated by the droplet on the surface are imaged, wherein the imaging is over a time course during which the droplet spreads on the surface. A droplet parameter is determined from the imaging step and a process parameter controlled to obtain an interference fringe pattern corresponding to a desired droplet parameter. In this manner, well-controlled droplet spreading is achieved, which is important in a range of applications, including assays that rely on good metaphase spreading.

Abstract: Mobile communication devices and integrated circuits thereof are provided. The mobile communication device, communicating with a packet switched network and a second network, includes a transceiver, a first PLL circuit and a controller. When exchanging an ongoing data transmission with the packet switched network, the transceiver transmits a first message to the packet switched network, which indicates the mobile communication device will be tuned away from the packet switched network, and performs a subsequent procedure for the second network. The first PLL circuit provides a first clock to the transceiver. When the ongoing data transmission with the packet switched network is not completed, the controller controls the first PLL circuit to switch the first clock from a first clock frequency to a second clock frequency after the transceiver transmits the first indication message.

In the mobile communication device, a wireless module performs wireless transmissions and receptions to and from a service network. Also, a controller module transmits an access probe to the service network via the wireless module, and retransmits the access probe in response to not receiving an acknowledgement of the access probe from the service network via the wireless module in a waiting period of time. The waiting period of time is determined according to a coherence-time related offset. The controller module further repeats the retransmission of the access probe until the acknowledgement of the access probe is received from the service network via the wireless module.

Abstract: A system and method of enhancing transmission of highly detectable pilots (HDPs). At least one base station transmits at least one cellular signal in which each cellular signal includes repetitive HDP cycles. Each HDP cycle has a duration of N power control groups (PCGs) and includes an HDP period having a duration of M PCGs in which N is greater than M. Traffic and overhead channels are gated during each HDP period. An enhanced HDP symbol is transmitted during a selected HDP period for each set of X HDP cycles of each cellular signal. For single carrier configurations, only one enhanced HDP is transmitted at a time, or multiple HDPs are transmitted in different directions. Standard 1x pilots may be transmitted. The enhanced HDP may be a boosted standard 1x pilot or an additional standard HDP pilot. Multicarrier configurations are described with PCG or sub-chip and/or phase offsets.
