Abstract: A droplet delivery device includes a housing with a mouthpiece port or outlet from a nasal device for releasing fluid droplets, a fluid reservoir, and an ejector bracket having a membrane positioned between a mesh with a plurality of openings and a vibrating member that is coupled to an electronic transducer, such as an ultrasonic transducer. The transducer vibrates the vibrating member which causes the membrane to push fluid supplied by the reservoir through the mesh to generate droplets in an ejected stream released through the outlet.

Abstract: A ride sharing implementation includes a system for logically grouping users. The logical groups may include one or more users designated as riders and one or more users designated as drivers. Notifications for ride requests submitted by or on behalf of riders are transmitted to drivers who can then accept the requests to coordinate transportation of the riders. Example personal monitoring devices and mobile applications for facilitating ride sharing are also provided.

Abstract: An osteotome includes a connector, a first arm, a second arm, a third arm, a fourth arm and a cutting head. A coordinate system has an X axis, a Y axis, and a Z axis. The X axis, the Y axis and the Z axis are perpendicular to each other and intersect at an original point. The connector extends along the Y axis. The first arm, extending along the Y axis, connects to the second arm, extending along the plane with the X and Y axes. An angle between the first and second arms is within a range between 125 to 145 degrees. The third and fourth arms respectively extend along the Z axis and the X axis. The cutting head is parallel to the X axis and the Y axis so as to easily control the insertion angle of the osteotome for the patients with smaller face or smaller oral cavity.

Abstract: An apparatus for detecting bone defects includes a detecting device and a dental abutment wirelessly connected to each other. The dental abutment includes a vibration component, at least one vibration excitation transducer, and at least one response sensor. The vibration component is used for being inserted in a dental implant. The vibration excitation transducer is disposed at one side of the vibration component for exciting the vibration component to vibrate, and the vibration excitation transducer is spatially separated from the vibration component. The response sensor is disposed at a side of the to vibration component opposite to the vibration excitation transducer for detecting the vibration of the vibration component.

Abstract: A lens actuating device is applicable in a lens module. The lens module has at least a housing and a lens support in the space formed by the housing. The lens actuating device has at least a base disposed in the housing, a piezoelectric element disposed on the base for generating kinetic energy, a clamping component disposed on the piezoelectric element and a linkage element coupled to the lens support and clamped in the clamping component. The clamping component makes a corresponding motion upon receiving a kinetic energy created by the piezoelectric element, which allows a stick-slip friction to be generated in the clamping component to actuate the lens, thereby achieving optical zooming or focusing and avoiding the shortcomings of the prior art using for example a voice coil motor or a stepping motor.

Abstract: An electronic device comprises a conductive device having a first end and a second end, a first element and a second element. The first element disposed on the first end of the conductive device generates a first temperature. The second element disposed around to the second end of the conductive device is switchable between a standby mode and an operation mode. The first temperature conducted from the first end to the second end shortens a warm-up time for the second element transferring from the standby mode to the operation mode.
