Abstract: A colposcopy instrument (which includes a display screen) is controlled by a specific set of steps defined in software to follow a defined protocol for performing a colposcopy examination. The software is utilized to also control the features of an included camera so that consistent digital images are recorded. The integrated software prompts the medical personnel performing the colposcopy procedure to capture relevant images in an automated sequence that includes, for example, capturing a sequence of images after the application of the acetic acid to the cervix. The displayed user interface guides the individual performing the exam through a series of easy-to-understand screen prompts to capture specific, critical images during the exam. The process, once begun, is automated and does not require the individual performing the exam to make any decisions about whether or not to record a certain image.

Title: System information protection at a network function in the core network
Inventor: LEE SOO BUM
IPC: H04W12/04
Filed: 2020-10-09
Abstract: Methods, systems, and devices for wireless communications are described. Private keys may be maintained upstream in a network at a more secure location. For example, when a signature is needed, a base station may transmit a signing request to a signing function within the core network and may transmit system information (SI) to be protected. The signing function may use a private key to generate a signature for the SI and returns the signature to the base station. The base station may transmit the SI and the signature to user equipment (UEs) within a coverage area of the base station. The UEs may obtain a public key corresponding to the private key and may use the public key to verify that the signature for the SI is valid and from the base station. The public key, and hence the signature, may correspond to a particular tracking area.
