Abstract: A method and apparatus for an inline air purification system 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. The housing is located in an HVAC duct, and occupies only part of the cross-sectional area of the duct. The remaining area of the duct accommodates bypass air flow to a primary fan in the HVAC system.

Abstract: In a method of managing access codes, a product is provided with an access restricting mechanism configured to permit operation of the product in response to entry of either one of first and second access codes using a code interface. The first access code is displayed on the product without displaying the second access code on the product. The second access code is identified to a user in response to user input of at least one of the first access code and a serial number into a terminal in communication with an electronically accessible code storage unit associating the second access code with the at least one of the first access code and the serial number.

Abstract: A capacitive touch keypad assembly includes a housing, a capacitance sensing substrate disposed within the housing, and a plurality of conducting members. The housing includes a barrier panel and a keypad display disposed on an exterior surface of the barrier panel. The keypad display defines a plurality of key locations each aligned with a corresponding bore in the barrier panel. The capacitance sensing substrate includes a plurality of key sensors in alignment with the corresponding plurality of key locations. Each of the plurality of conducting members has a first end disposed in a corresponding one of the plurality of barrier panel bores and a second end engaging a corresponding one of the plurality of key sensors.

Abstract: A battery operated device includes a housing, an operating mechanism and an internal battery disposed within the housing, and an access member assembled with the housing and movable between first and second positions. The operating mechanism includes first and second sets of electrical contacts for transmitting power to the operating mechanism, with the internal battery being electrically connectable with the first set of electrical contacts for powering the operating mechanism. The access member is movable between a first position blocking external access to the second set of electrical contacts and connecting the first set of electrical contacts to the internal battery, and a second position permitting external access to the second set of electrical contacts and disconnecting the internal battery from the first set of electrical contacts.

Abstract: A lock includes a lock body, a lock bar, and a locking mechanism. The lock body extends in a longitudinal direction between a first end defining a longitudinal passage and a second end. The lock bar is disposed within the passage and movable in a longitudinal direction between a securing position proximal to the second end and a release position distal to the second end, with a proximal end portion of the lock bar and the second end defining a first gap when the lock bar is in the release position. The locking mechanism is assembled within one of the lock body and the lock bar and is operable between a locking condition securing the lock bar against movement from the securing position to the release position, and an unlocked condition permitting movement of the lock bar from the securing position to the release position.
