Abstract:
Devices having a handle that provides unlimited roll to an end-effector at the distal end of the device. For example, described herein are medical devices that have an elongate tool frame, an end-effector, and a handle that includes: a first portion, a second portion that rolls relative to the first portion, a push rod within the first portion connected to a control input, and a shuttle body within the second portion that rotates with the second portion but is axially driven by the push rod when the user actuates the control input. The device may include a proximal wrist/forearm attachment allowing one or more degrees of freedom in pitch, yaw or roll about the user's arm. The handle may articulate relative to the tool frame, and this articulation may be transmitted to the end-effector. The end-effector may be a jaw assembly.
Abstract:
An application running on a user device may communicate with a server application. The server application may track user actions on the device. The user actions may be transmitted from the user device to the server application using data packets. Each data packet may include header information and information regarding one or more user actions (the “batch”). The number of user actions to include in each batch may be determined by the OS, by the application, by the user, by the network, the number of actions in the batch, the size of the data in the batch, the time elapsed between the first and last action in the batch, or any suitable combination thereof. A communication server may recognize a batch data packet and divide it into individual data packets.

Methods for treating tooth sensitivity are also disclosed.
Abstract:
Disclosed is a process for the production of d-tagatose from lactose after acid hydrolysis to provide a hydrolysate having 1 equiv of d-glucose and 1 equiv of d-galactose for each unit of lactose converted. More particularly, the invention relates to a process for the isomerization of d-galactose to d-tagatose and the use of a simplified separation scheme based on simulated moving bed (SMB) separation. The isomerization of d-galactose to d-tagatose is carried out in the presence of calcium oxide or calcium hydroxide. The process is useful for providing a simplified processing route to providing pure d-tagatose and glucose as two products from lactose hydrolysate. In an alternate embodiment, a process is disclosed for the production of d-tagatose from fermented lactose hydrolysate to provide a crystallized d-tagatose product. D-tagatose is useful as a food additive, as a sweetener, as a texturizer, as a stabilizer, or as a humectant.
Abstract:
A four terminal field effect device comprises a silicon field effect device with a silicon N-type semiconductor channel and an N+ source and drain region. An insulator is deposited over the N-type semiconductor channel. An organic semiconductor material is deposited over the insulator gate forming a organic semiconductor channel and is exposed to the ambient environment. Drain and source electrodes are deposited and electrically couple to respective ends of the organic semiconductor channel. The two independent source electrodes and the two independent drain electrodes form the four terminals of the new field effect device. The organic semiconductor channel may be charged and discharged electrically and have its charge modified in response to chemicals in the ambient environment. The conductivity of silicon semiconductor channel is modulated by induced charges in the common gate in response to charges in the organic semiconductor channel.
