Abstract: A secure enclave may be used to satisfy privacy requirements and audit requirements. Code may be loaded into the secure enclave. The code may generate a predefined report based on data and added noise. The pre-defined report may be subject to audit requirements. The data may be subject to the privacy requirements. The secure enclave may generate an encryption key and a decryption key based on the code. Only the secure enclave may have access to the decryption key. And the secure enclave may allow only a verified copy of the code to access the decryption key. With the added noise, the report may satisfy a pre-defined differential privacy guarantee. Encrypting the code and ensuring that the report satisfies the differential privacy guarantee may satisfy the privacy requirements. Retaining the report, the code, the secure enclave, and the encrypted data may satisfy the audit requirements.

Abstract: An ear was removal device, having a rod-shaped elongated member, and at least one concave, dome shaped scraping end rigidly affixed to the elongated member of a size sufficient to permit insertion into the ear canal without causing injury to the ear and without pushing a substantial quantity of ear wax further into the ear canal. The ear removal device further has, an option, a cotton swabbing member. The ear removal device can also include two scraping ends each affixed to one end a piece of the rod-shaped elongated member. The member can be comprised of a polymeric substance and/or a cottononous substance.

Abstract: A mobile device for forcing a highway post into the ground in the vertical position, especially where the highway post is flexible and made of fiberglass, which involves a vertical column spaced from and supported by the mobile device, guide means mounted on the vertical column to hold a reflective highway post in a vertical position while the post is forced into the ground by repetitive blows from a hydraulically driven hammer and means for moving the vertical column and the guide means upwards in a vertical direction when the post has been forced a sufficient distance into the ground.

Abstract: A self-propelled concrete cutting saw in which the saw and self-propelled platform associated with the saw are both driven by hydraulic motors, with separate motors for each of the two propelling wheels so that the device may be steered by varying the speed of either of the wheels, with the speed of longitudinal movement of the saw through the concrete being controlled by the density of the concrete being cut by the saw so that the saw blade is operated at an optimum rotational speed.

Abstract: A device for cutting slots of varying lengths and shapes in pavement to receive a reflector, the cutting blades for cutting the slot always being at right angles to the tangent to that portion of the surface of the pavement where the slot is being cut and means permitting the cutting blades to be maintained at an optimal rotational speed regardless of the density of the type of pavement encountered.

Abstract: A device for cutting a receptacle in pavement to receive a reflector designed to reflect automobile lights, which reflector is contained in a housing so that it is protected from a snowplow mold board during normal plowing operations. Such reflectors are becoming standard in separating traffic lanes and are embedded in the pavement in epoxy. The device simultaneously cuts a receptacle of a shape such that the reflector and its protective cast iron housing may be readily inserted in the pavement. The device enables the receptacle to be cut at right angles to a tangent to the curved portion of the crown of the road, permits rapid exact positioning of the receptacle location and enables the receptacle to be formed in approximately five seconds.

Abstract: A bracket support assembly is provided by the combination of a semiflexible web having holes therein for operatively receiving and supporting a portion of an article holding bracket and having spacing means extending away from one face of the semiflexible web, a semiflexible holding member disposed on the face of the web opposite the flange, the holding member having adjustable means for receiving and retaining a portion of the article holding bracket, and adjusting means disposed in the semiflexible web for adjusting the adjustable means of the holding member.
