TL;DR: A guard for the tip of a hypodermic needle which is activated automatically when the needle is withdrawn after use is described in this article. But the mechanism is not described in detail.
Abstract: A guard for the tip of a hypodermic needle which is activated automatically when the needle is withdrawn after use. The guard resides initially around the shaft of the needle near the needle tip. Insertion of the needle causes the guard to be pushed back by the surface of the skin. This releases the spring activated locking mechanism such that when the needle is withdrawn the spring pushes the guard over the tip of the needle and the guard becomes automatically locked in place.

TL;DR: In this paper, a guard is designed for use with a wall-mounted light switch in order to keep the switch in the desired "on" or "off" state, by pivoting out of the way when it is desired to allow access to and operation of the light switch.
Abstract: A protective guard for use with a wall-mounted light switch in order to keep the light switch in the desired "on" or "off" state. The guard is a pivotal arm having at one end an opening for receiving one of the mounting screws of the light switch, by which the guard is pivotally connected to the wall plate of the light switch. When it is desired to allow access to and operation of the light switch, the guard is pivoted out of the way. The same general principle of the invention applies to a guard for selectively closing off a wall plug outlet.

TL;DR: In this paper, a ladder side rail is equipped with a rigid body and a resilient pad to prevent the surface against which the ladder rests from being marred, and the resilient pad is replaceable as it loses its resiliency or otherwise wears out.
Abstract: A guard for the upper end of a ladder side rail telescopes over said upper end to prevent the surface against which the ladder rests from being marred. The guard includes a rigid body and a resilient pad removably affixed to the body. The resilient pad engages the surface for preventing said marring. The resilient pad is replaceable as it loses its resiliency or otherwise wears out so that the entire guard does not have to be replaced, whereby the effectivity, usefulness and cost effectiveness of the guard is enhanced.

TL;DR: This thesis establishes tight bounds on the maximum size of maximum hidden sets, minimum guard sets, and minimum partitions and covers of polygons, using link-visibility, and proves that the optimization problems of finding maximum hidden set, minimumguard sets, or minimum covers are NP-hard.
Abstract: In this thesis, we establish tight bounds on the maximum size of maximum hidden sets, minimum guard sets, and minimum partitions and covers of polygons, using link-visibility. These results unify and generalize the guard set results (and combinatorial method) of Chvatal and O'Rourke. Our method also provides tight bounds on independent and dominating sets in triangulation graphs, and almost-tight bounds on the size of hidden sets, guard sets, covers, and partitions of polygon exteriors. We also prove that, using link-visibility, the optimization problems of finding maximum hidden sets, minimum guard sets, or minimum covers are NP-hard.
Link-visibility is an extended notion of visibility arising from robotics and motion planning problems. Hidden sets are sets of points in a polygon such that no two points of the set are visible, and guard sets are sets such that each point of the polygon is visible to some point in the guard set. Both maximum hidden set sizes and minimum guard set sizes can be used as polygon shape complexity measures.

TL;DR: In this article, a side guard for protecting vehicles is attached at its ends to recessed securing mechanisms located in the wheel wells or elsewhere in the vehicle body, which can be locked into place to prevent unauthorized removal.
Abstract: A side guard for protecting vehicles is attached at its ends to recessed securing mechanisms located in the wheel wells or elsewhere in the vehicle body. The guard is a belt or tubular molding of rubber or plastic which can be locked into place to prevent unauthorized removal. The guard can be positioned and configured to provide maximum protection of the vehicle, is easy to attach and remove, and can be effectively locked in place. An electrical circuit formed in the guard can be connected to an alarm system. The locking mechanism can be electrically actuated by a vehicle locking system, e.g. by unlocking the door.

TL;DR: The study demonstrated that a significant improvement could be seen when the same number of guards worked two parallel traffic lines leading to the single gate, instead of working in a serial process from a single line of traffic.
Abstract: We were asked to improve the time it took a queue of cars to go through a security gate every morning and afternoon. Each individual passing through the gate was required to show a security badge to a guard. The goal was to improve processing time and to eliminate a safety problem at the gate without increasing the required resources. This problem required quick resolution. The project was initiated using queuing theory. After collecting data, we determined that a simulation model would be more appropriate. The study demonstrated that a significant improvement could be seen when the same number of guards worked two parallel traffic lines leading to the single gate, instead of working in a serial process from a single line of traffic.

Abstract: PURPOSE: To facilitate maintenance work by fixing curve-shaped guard members on the extreme ends of arms journaled rotationally movably outward on the upper ends of a plurality of pillars standingly provided outside the gauge of a main line behind an abutment. CONSTITUTION: A plurality of pillars are standingly provided in parallel with rails 12 outside the gauge of main line rails 12 laid behind an abutment 11. Nextly, rotationally movable arms 15 in the right-angled direction against the laying direction of the rail are journaled with supporting shafts 16 on arm fitting tools 14 fixed on the upper ends of the pillars, and curved guard members 17 gradually spread facing to the terminal parts are fixed and arranged on the extreme ends of the arms 15 with bolts and nuts 18. At tamping ballast, the guard members are rotationally moved outward, after completion of the work the arms are rotationally moved inward to return to the initial position. Hereby, the maintenance work can be facilitated. COPYRIGHT: (C)1991,JPO&Japio

TL;DR: An interlocking door guard securely covers and is attached to the outside of doors that open inward as discussed by the authors, which uses a full length pendulum torsion rod assembly on the hinge side of the door as well as guides in connection therewith and matching receptacles in and/or on both vertical casing members to accommodate mating sections of door guard.
Abstract: An interlocking door guard securely covers and is attached to the outside of doors that open inward. It uses a full length pendulum torsion rod assembly on the hinge side of the door as well as guides in connection therewith and matching receptacles in and/or on both vertical casing members to accommodate mating sections of door guard. The forward section has an open area adequate to access door locks. This area is further protected by adjustable guard bars. Hinge lever assemblies attached to the door and guard in the forward area cause it to shift and interlock and disengage both vertical casing members when encountering stop plates on forward casing receptacles.

TL;DR: A ski pole hand guard is intended to be mounted on a ski pole directly below the hand grip as mentioned in this paper, which is used to protect a skier's hand during a fall and protect it from the initial contact made during a normal fall.
Abstract: A ski pole hand guard is intended to be mounted on a ski pole directly below the hand grip. This hand guard includes a pole attachment member and a cup-shaped, almost semi-circular guard member which surrounds the hand grip in an arc of less than 180° and projects outwardly slightly beyond the normal distance needed to clear a skier's ski glove. A top flange member extends from the top edge of the guard member inwardly towards the center line of the ski pole. The hand guard structure is constructed of durable, impact resistant material and is rigidly attached to the pole attachement member. When in use, the skier grasps the ski pole hand grip as normal and has the first joint of his thumb and the first, second and third joints of his fingers within the bounds of the guard member and flange memner. The hand guard sufficiently surrounds a skier's hand to retain it during the initial fall reflex and protect it from the impact of the initial contact made during a normal fall. It is sufficiently small to reduce the possibility of wrist injury and to allow easy hand release.
