A cane includes a tube, an extension rod telescopically mounted within one end of the tube, and a control mechanism sandwiched between the tube and the extension rod. The tube defines a first aperture and a second aperture. The extension rod defines a plurality of holes. The control mechanism is movable among a first position where the control mechanism is positioned in a selected one of the holes in the extension rod, and the tube, the extension rod and the control mechanism are prohibited from moving axially with respect to one another; a second position where the extension rod and the control mechanism together are allowed to move axially with respect to the tube; and a third position where the extension rod is allowed to move axially with respect to the control mechanism and the tube.

A method for immobilizing glycoprotein is disclosed. A surface is provided. Next, a boronic acid is contacted to the surface. The boronic acid is represented as Y—R—B—(OH)2 and includes a boronic acid group (B—(OH)2), a linker R, and a functional group Y, in which the boronic acid is bonded to the surface via the functional group Y. A glycoprotein is contacted to the boronic acid, wherein two spatially adjacent hydroxyl groups of a carbohydrate chain form a boronate ester with the boronic acid group of the boronic acid to immobilize the glycoprotein. The goal of site-specific and covalent protein immobilization without interfering the binding affinity of an antibody to antigen may be thus achieved with the reaction of boronic acid and the carbohydrate chain of Fc region.

An integrated high-speed package comprising a package housing having a housing lip and connector having a center pin abutting along a bottom surface of the housing lip. For signal registration of a first substrate to the signal lead, the substrate is “floated” up to the housing lip, which provides an alignment reference to ensure that the top surface of the first substrate is aligned and in direct registration with the signal lead. In another embodiment, the center pin to substrate registration is provided at a top surface of a housing base. The housing base preferably comprises a first portion of a first height and a second portion of a second height. Accordingly, the housing base can accommodate substrates of different thickness while allowing a top surface of the first and a second substrate to be coplanar to facilitate signal registration there between.

An apparatus and method for hermetically sealing, EMI shielding integrated circuits for high-speed electronic devices using a combination of microstrip to buried stripline interface for signal transmission from the integrated circuit. The packaging provided comprises a first plurality of microstrips interconnecting the integrated circuit to a plurality of buried striplines exposed on a surface of the main substrate. A ceramic interposer placed over the main substrate “buries” a portion of the exposed striplines on the main substrate to thereby insulate these signal paths from a hermetically sealing, and EMI shielding metal lid placed over the integrated circuit. The metal lid and the seal ring brazed over the ceramic interposer thus provide both a hermetic seal and an electric radiation block. A reduction in dispersion due to the buried striplines is also achieved, as well as improving jitter performance.

A temperature and humidity sensing device including a body and a temperature and humidity sensor is provided. The body has an inlet hole, an outlet hole, and a flow channel. The inlet hole and the outlet hole are opposite to each other, and the flow channel is configured to communicate the inlet hole and the outlet hole. The temperature and humidity sensor is disposed in the flow channel. The temperature and humidity sensor is configured to sense the relative humidity of air in the surrounding environment of the body during the air in the surrounding environment of the body flows into the flow channel from the inlet hole and flows through the flow channel to flow out from the outlet hole.

A gaming system is disclosed comprising a console unit having a processor and transceiver circuitry. The transceiver circuitry couples to the processor and includes respective receiver and transmitter circuits. A first phased array antenna interface is employed to transmit and receive directional signals in response to the processor. The system employs a mobile game controller including a second phased array antenna interface to receive and redirect the directional signals back to the first phased array antenna interface. The processor generates proximity data based at least in part on a parameter associated with the directional signals, the proximity data representing the proximity of the mobile game controller with respect to the game console unit.
