Abstract: A method of restoring an image of a computer, including identifying, by a backup application executing on the computer, artifacts of the computer to back up, creating a mirror image of a hard drive of the computer, wherein the mirror image comprises the artifacts, establishing a local environment within the computer, communicating with a backup server, by the backup application, using the local environment in the computer, backing up the mirror image, by the backup application, to the backup server using the local environment, updating the mirror image, by the backup application, in the backup server in response to a change in the computer, constructing the local environment on the computer in response to an event, loading a program from the local environment, and restoring the computer, by the backup application, from the mirror image in the backup server based on the artifacts, the program, and the restore process.

Abstract: The present disclosure provides laminates, which include adhesive materials and methods that allow for the removal of contaminants, e.g. particulate contaminants, from a substrate surface. In one embodiment, the laminates include (i) a substrate with contaminant disposed on its surface, (ii) a liquid, adhesive precursor and (iii) a film layer. The liquid, adhesive precursor is disposed between the substrate and the film layer. In another embodiment, the laminates include (i) a substrate with contaminant disposed on its surface, (ii) a cured adhesive layer and (iii) a film layer. The cured adhesive layer is disposed between the substrate and the film layer. The laminates may be used to remove contaminant from the substrate surface by removal of the film layer and the cured adhesive layer, which entraps the contaminant therein.

Abstract: A method at an electronic device with a display includes: displaying a user interface having a first region and a second region; receiving, and displaying in the first region of the user interface, a live video stream of a physical environment captured by a remote video camera; displaying, in the second region, a timeline corresponding to a timespan for a first portion of a duration during which the live video stream may have been recorded; in response to receiving a user interaction to move the timespan to a second portion of the duration, transitioning the displayed timeline to a new timeline that corresponds to the timespan for the second portion, and while transitioning, displaying, in the first region, a subset of video frames representing the first and/or second portion of the duration.

Abstract: Kits for converting a single-speed bicycle to a multi-speed bicycle are described. Such kits typically include a front chainring set having 2-5 differently-sized front chainrings, a front derailleur compatible with the front chainring set, a front derailleur shifting assembly compatible with the front derailleur, a chain tensioner, and a chain sized to accommodate the gearing provided by the plurality of front chainrings and the existing or new rear sprocket(s) to be fitted to the rear wheel of the bicycle undergoing the conversion.

Abstract: A time delay shifter imparts a constant time delay to an electromagnetic signal, preferably a signal at a microwave frequency, over a band of frequencies. The phase shift imparted to the signal is a linear function of frequency. The shifter comprises a finite number of delay units (1) each having four single-pole single-throw switches (11-14). Closure of the first and third switches (11, 13) causes the signal to traverse a first path (2) containing a preselected length of transmission line that imparts a fixed time delay to the signal. Closure of the second and fourth switches (12,14) causes the signal to traverse a minimum-delay path (3) which is shorter than the delay path (2). The paths (2,3) are fabricated of coplanar waveguide. Each switch (11-14) is resonated by an inductor (21-24) for purposes of increasing isolation. An attenuator (70) is inserted in each minimum-delay path (3).

Abstract: A coin-box placed adjacent to a television receiver is interposed in the path of a signal input line that supplies program signals to the receiver. Signals on some program channel (the "free" channels) are permitted to pass through the coin box at all times. The purpose of the coin box is to require payment for the reception of programs on certain other selected frequency channels (the "pay" channels). One or more band rejection filters (frequency traps) are utilized within the coin box to normally prevent reception of the pay channels. A bypass circuit, controlled by a relay, permits the pay channels to be received during time periods that have been paid for. The coin-box is lockable for security purposes and contains a timing circuit, a relay, and other controls. The selection of pay channels as well as the various control parameters may be adjusted at will by the proprietor of the establishment in which the television set is located.
