Abstract: A method and apparatus for processing air is described herein. An example apparatus includes a housing, a high-velocity air flow guide, a filter assembly, and a fan. The high-velocity air flow guide includes a first portion and a second portion. The first portion is configured to form a passage within the housing, and the second portion is configured to divert and accelerate air flow of the ambient air from the passage to a chamber of the housing. The filter assembly includes one or more filtering elements configured to receive the ambient air from the chamber. The fan is configured to draw the ambient air from the chamber through the filter assembly and to generate processed air from the ambient air.

Abstract: An alarm device for use with a vehicle includes an input connector for electrical connection with a vehicle wiring harness of a vehicle, an output connector for electrical connection with a trailer lighting receptacle of a trailer, and an alarm circuit electrically connected in series between the input connector and the output connector. The alarm circuit is configured to detect a presence or absence of an electrical signal supplied to the input connector for delivery through the output connector to an electrically powered component of the trailer. The alarm circuit is configured to deliver an alert signal when the alarm circuit detects the absence of the electrical signal.

Abstract: A mountable lock includes a lock body and a retaining member. The lock body is configured to be secured to an external structure by at least one fastening member. The lock body includes a lock interface movable from a locking condition to an unlocking condition in response to proper user manipulation of the lock interface. The retaining member includes a first end receivable in a first opening of the lock body and lockingly engageable with the lock body when the lock interface is in the locking condition, the first end being disengageable from the first opening when the lock interface is in the unlocking condition. The at least one fastening member is accessible through a passageway in the lock body that is blocked when the retaining member is in locking engagement with the lock body, thereby preventing disassembly of the lock body from the external structure.

Abstract: An assembly for restricting access to a coupler includes a body having a coupler engagement portion for engagement with a first surface of a coupler, a coupler engagement member laterally movable within a laterally extending slot in the body, with the coupler engagement member extending perpendicularly from the slot for engagement with a second surface of the coupler opposite the first surface. The assembly further includes a securing mechanism for selectively securing the coupler engagement member relative to the body against lateral movement away from the coupler engagement portion. When at least a portion of the coupler is received between the coupler engagement portion and the coupler engagement member and the coupler engagement member is secured in a coupler lockout position, at least one of the coupler engagement portion and the coupler engagement member prevents withdrawal of the coupler from the assembly.

Abstract: A trailer hitch mountable device for installation in a trailer hitch receiver tube includes a housing and a retainer bracket. The housing is sized to be received in the receiver tube and has an outermost wall including at least a first arcuate portion sized to align with circumferential edges of aligned mounting holes of the receiver tube when the device is installed in the receiver tube. The retainer bracket is secured to the housing and configured to engage an outermost edge of the receiver tube when the device is installed in the receiver tube. When the device is installed in the receiver tube and a receiver pin is inserted through the aligned mounting holes, the first arcuate portion prevents movement of the housing toward the outermost edge of the receiver tube, and the retainer bracket prevents movement of the housing away from the outermost edge of the receiver tube.

Abstract: A locking device includes a shaft, a locking head joined to the shaft, and a lock body having a lock opening for receiving a locking end of the shaft. A latch member is disposed within the lock body and includes a shaft aperture for receiving the locking end of the shaft therethrough. The shaft aperture includes an edge portion spring biased radially inward of the lock opening to engage the recessed portion with the edge portion when the locking end of the shaft is disposed in the lock opening. A locking member is disposed within the lock body. Rotation of the locking member from a locked condition to an unlocked condition moves the edge portion of the shaft aperture out of engagement with the recessed portion of the shaft to permit withdrawal of the shaft from the lock opening.

Abstract: A portable safe for assembly with an apertured member includes a safe housing and a safe door. The safe housing has an internal cavity extending to an access port, and at least one opening configured to align with at least one aperture of the apertured member. The safe door is securable to the housing to substantially block the access port. The safe door includes a locking mechanism having at least one locking member secured in a housing engaging position when the locking mechanism is in a locked condition. The at least one locking member is movable to a housing disengaging position when the locking mechanism is in an unlocked condition. The safe door further includes a lock interface that is selectively operable to move the locking mechanism from the locked condition to the unlocked condition.

Abstract: A trailer/cargo alarm detects the proximity of trailer or cargo attached to a vehicle with an alarm system. If the trailer/cargo is moved out of proximity of the vehicle, the alarm system issues an alert. The proximity of the trailer or cargo may be detected, for example, by detecting the presence of the trailer lighting within the vehicle's electrical circuit, by dedicated hardwired sensors, or wireless detection apparatus.

Abstract: An assembly for restricting access to a coupler includes a body having a coupler engagement portion for engagement with a first surface of a coupler, a coupler engagement member laterally movable within a laterally extending slot in the body, with the coupler engagement member extending perpendicularly from the slot for engagement with a second surface of the coupler opposite the first surface. The assembly further includes a securing mechanism for selectively securing the coupler engagement member relative to the body against lateral movement away from the coupler engagement portion. When at least a portion of the coupler is received between the coupler engagement portion and the coupler engagement member and the coupler engagement member is secured in a coupler lockout position, at least one of the coupler engagement portion and the coupler engagement member prevents withdrawal of the coupler from the assembly.

Abstract: For a cargo alarm system cargo is secured to a storage location, such as, for example, a vehicle by coupling a signal carrying device between the storage location and the cargo. The signal carrying device, which may be, for example, a flexible electrically conducting tether, provides a closeable alarm signal loop between the storage location and the cargo. An alarm signal is transmitted on the signal carrying device and in turn the alarm signal is received on the signal carrying device. An alert signal is provided when the alarm signal is not received from the signal carrying device.
