A system for cleaning bone that includes a base unit with a motor, a cleaning head with a cleaning element and a mill head with a mill element. Both the cleaning head and the mill head are designed to be coupled to the base unit. Both the cleaning element and mill element have features that facilitate their coupling to the motor. When the cleaning head is attached to the base unit, a motor in the base unit rotates the cleaning element to remove soft tissue from the bone so as to clean the bone. The mill element is placed on the base unit and the cleaned bone placed in the mill head. The actuation of the base unit motor results in the actuations of the mill element. The actuation of the mill element converts the cleaned bone into bone chips.

System for processing bone stock including a bone cleaning head, a bone milling head and base that powers both the cleaning head and the milling head

Visually enrolling a camera using an optical code and a picture file, including: receiving the picture file and the optical code from the camera, wherein the optical code includes a public key of the camera; generating a visual challenge using a nonce created by a random number generator; transmitting the visual challenge to a user of the camera to capture the visual challenge; receiving the captured visual challenge from the camera; extracting a response from the captured visual challenge; comparing the response to the nonce to verify a signature of the captured visual challenge using the public key of the camera and to convert the optical code received from the camera into a valid certificate; and enrolling the camera and adding the valid certificate to a key store.

Visual enrollment of cameras

Authenticating a user account to access a remote service from a user device includes: capturing a machine-readable image code displayed on the user device using a mobile device, wherein the image code is provided by the remote service; extracting and calling a corresponding session code embedded in the image code; determining whether a phone token is in storage; one of: (a) sending the phone token to the remote service, if the phone token is in the storage; or (b) prompting a user to enter credentials including username and password and sending the entered credentials to the remote service, if the phone token is not in the storage; and receiving access to the remote service for the user device, when the session code is valid and either the credentials are valid or the phone token is confirmed.

Code-based two factor authentication

Fixity data processing of a file by an ingester, including: receiving and processing the file by slicing the file into a plurality of parts; calculating a digest of each part until digests of all of the plurality of parts have been calculated; calculating a master hash as a combination of the digests of all of the plurality of parts; calculating a master hash signature using the master hash and a private key of the ingester; forming a fixity data including a set of digests which includes digests of all of the plurality of parts, the master hash, the master hash signature, and a public key of the ingester; sending the fixity data to a verifier; and storing, in a trusted database, a fixity metadata including the master hash, the master hash signature, the public key of the ingester, and an identifier of the file.

Fixity data processing

Encrypting a document, including: generating first and second nonces; combining the first and second nonces to generate a secret key that is deterministically defined by the first and second nonces; encrypting the document using the secret key to produce an encrypted document; delivering the first nonce to a license manager; and delivering the second nonce to a rights manager.

Re-encryption-based digital rights management

Distributing and enforcing a license for content to be consumed according to conditions defined by usage rights stated in the license, including: encrypting the usage rights with a key using a homomorphic encryption and sending the encrypted usage rights to an agent; receiving from the agent modified encrypted usage rights generated by performing a homomorphic operation on the encrypted usage rights with a nonce; and decrypting the modified encrypted usage rights and sending the decrypted modified usage rights back to the agent, wherein usage rights are extracted from the decrypted modified usage rights by performing an operation that is reverse of the homomorphic operation with the nonce.

User-protected license

Authenticating for a virtual reality (VR) system using a plurality of factors of authentication, including: collecting a password entered into a virtual keyboard for a first factor of the plurality of factors of authentication, wherein the password is entered by a user selecting a series of data including numbers, letters, or images on the virtual keyboard displayed on a display of the VR system; and collecting a biometric fingerprint from movements of the VR system for a second factor of the plurality of factors of authentication.

Multi-factor authentication for virtual reality

A surgical system comprises a handpiece and a battery. The handpiece includes a body and a handpiece connector operatively coupled to the body, the handpiece connector including a first coupler. The battery includes a housing, a rechargeable cell for storing an electric charge, and a battery connector operatively coupled to the housing, the battery connector including a second coupler configured to rotatably engage the first coupler. The second coupler receives the first coupler along an axis at an initial radial position where relative axial movement between the battery and the handpiece is permitted and permits rotation of the battery relative to the handpiece from the initial radial position to a first secured radial position and a second secured radial position. Relative axial movement between the battery and the handpiece is constrained in the first secured radial position and in the second secured radial position.

Surgical systems with twist-lock battery connection

Blockchain-based proof of presentation of content on a media channel, including: generating, upon receiving a request to generate, at least first, second, and third parameters, wherein the first and second parameters are input parameters and the third parameter is calculated as an output parameter of a one-way cryptographic function; generating a first type of block by incorporating the first and third parameters into the first type of block; validating the first type of block and the blockchain; appending the first type of block to the blockchain when both the first type of block and the blockchain are declared valid; and embedding the second parameter into the content that is to be made available on the media channel to produce tainted content.

Media channel monitoring to prove content presentation

Verifying that a user is using a device at a pre-specified location between a start time and an end time, including: calculating a challenge and an answer that is a function of the challenge; generating and storing in a blockchain, a commitment including an identity of the user, an identity of the device, the pre-specified location associated with the user, the start time of usage of the device, the end time of usage of the device, and the calculated challenge; generating a visual code of the device to carry the answer; encrypting the generated visual code with a public key of the device, wherein the encrypted visual code may only be decrypted with a private key of the device; and storing the encrypted visual code in the blockchain.

Four-factor authentication

A cleaning module for cleaning bone stock used in surgical procedures. The cleaning module includes a shell. The shell defines a void space to receive the bone stock. A cutter is rotating mounted in the void space. A shaving tube, also able to rotate, is coaxially disposed about the cutter. The cutter and shaving tube have complementary edges. A drive assembly rotates the cutter and shaving tube at different speeds, at different times or in different directions relative to the cutter. As a result of the rotation of the cutter and shaving tube soft tissue adhering to the bone stock is cut away from the bone stock by the relative rotating of the cutting edges of the cutter and shaving tube.

Bone cleaning assembly

A bone cleaning assembly () with cleaning elements () that remove soft tissue from bone stock. The module also includes a clearing element () that is periodically urged against the cleaning elements to remove bone stock trapped by the cleaning elements from the cleaning elements.
