Battery housing for powered surgical tool

A battery housing for a driver of a powered surgical tool. The battery housing includes a casing with an opening for inserting at least one battery into the casing, a door for closing the opening when the door is in its closed position, and a driver interface for removably attaching the battery housing to a driver of a powered surgical tool. The door includes at least one part that is configured for being blocked by the driver when the door is moved out of its closed position and the battery housing is attached to the driver, such that the door cannot be opened when the battery housing is attached to the driver.

ELECTRIC POWER TOOL

An electric power tool comprising a voltage conversion circuit configured to control magnitude of a voltage applied to a motor in accordance with magnitude of load.

Authentication system for reusable surgical instruments

An authentication system for use in a surgical stapling device includes an authentication board assembly disposed at a proximal end of a loading unit and having a contact assembly, and an adapter board assembly disposed at a distal end of an adapter assembly. When the loading unit is engaged with the adapter assembly, the authentication board engages the adapter board assembly.

Selective deposition of metals, metal oxides, and dielectrics

Methods are provided for selectively depositing a material on a first surface of a substrate relative to a second, different surface of the substrate. The selectively deposited material can be, for example, a metal, metal oxide, or dielectric material.

Introducer assembly for a surgical fastener applying apparatus

An introducer assembly can be releasably coupled to a surgical instrument and includes a collar, a tip, and an elongated body portion disposed between the collar and the tip. The tip may be configured to releasably engage a dissecting device. The collar may releasably couple the introducer assembly to a shaft of a surgical fastener applying apparatus. The tip may have an opening to receive a distalmost end of an end effector of a surgical fastener applying apparatus.

Multi-focal display system and method

Configurations are disclosed for presenting virtual reality and augmented reality experiences to users. The system may comprise an accommodation tracking module to track an accommodation of a user's eyes, a first variable focus element (VFE) to switch between at least two focal planes, wherein a distance between the two focal planes is relatively consistent, and a second VFE to shift the at least two focal planes based at least in part on the tracked accommodation of the user's eyes.

Multi-focal display system and method

Configurations are disclosed for presenting virtual reality and augmented reality experiences to users. The system may comprise a scanning device for scanning one or more frames of image data. The scanning device may be communicatively coupled to an image source to receive the image data. The system may further comprise a variable focus element (VFE) operatively coupled to the scanning device for focusing the one or more frames of image data on an intermediate image plane, wherein the intermediate image plane is aligned to one of a plurality of switchable screens. The plurality of switchable screens may spread light associated with the intermediate image plane to specific viewing distances. The system may also comprise viewing optics operatively coupled to the plurality of switchable screens to relay the one or more frames of image data.

Uniform communication protocols for communication between controllers and accessories

A uniform protocol can facilitate secure, authenticated communication between a controller device and an accessory device that is controlled by the controller. An accessory and a controller can establish a pairing, the existence of which can be verified at a later time and used to create a secure communication session. The accessory can provide an accessory definition record that defines the accessory as a collection of services, each service having one or more characteristics. Within a secure communication session, the controller can interrogate the characteristics to determine accessory state and/or modify the characteristics to instruct the accessory to change its state.

Anti-slip end-effector for transporting workpiece

An anti-slip end-effector for transporting a workpiece, which is configured to be attached to a robotic arm, includes: a workpiece-supporting area for placing a workpiece thereon for transportation; at least one front protrusion disposed at a distal end of the workpiece-supporting area for engaging an edge of the workpiece to restrict movement of the workpiece placed on the workpiece-supporting area beyond the front protrusion; and at least one anti-slip protrusion disposed in the workpiece-supporting area for contacting and supporting the backside of the workpiece, said anti-slip protrusion having a top face having a static friction coefficient of 1.0 or more as measured against the backside of the workpiece, and having a surface roughness of less than 0.4 μm.

Automated access, key, certificate, and credential management

Certain embodiments provide means for managing automated access to computers, e.g., using SSH user keys and other kinds of trust relationships. Certain embodiments also provide for managing certificates, Kerberos credentials, and cryptographic keys. Certain embodiments provide for remediating legacy SSH key problems and for automating configuration of SSH keys, as well as for continuous monitoring.
