A security alarm system which may be selectively armed or disarmed when monitoring a protected premises is described which utilizes the position of a deadbolt to determine whether the security system should be armed or disarmed. The security system comprises (i) an entry door for permitting ingress to the protected premises from the outside of the entry door and egress from the protected premises from the inside of the entry door; (ii) a lock for selectively locking and unlocking the entry door; and (iii) a switch having a first state indicative of the lock being in a locked position and a second state indicative of the lock being in an unlocked position wherein, when the switch is in its first state, the security system is armed and, when the switch is in its second state, the security system is disarmed. Sensing means are also provided to determine if the lock was engaged from inside or outside the protected premises. In the case where the lock was engaged from outside the premises and no authorized individual remains inside, sensors inside the premises would become activated. Conversely, in the case where the lock was engaged from inside the premises or from outside the premises and an authorized individual remains inside, the inside sensors would remain deactivated. The disabling of an inadvertent (false) alarm is easily, yet securely, achieved by activating a first user-controlled disarming means and returning the lock to its unlocked position.

In a Softail.RTM.-type motorcycle frame, a rear damper mounting bracket is connected to a threaded receiver, which is in turn connected to an adjuster plate. The adjuster plate has two longitudinal slots for fastening the adjuster plate to the swing arm lower cross member. An adjuster bracket is also connected to the swing arm lower cross member. An adjuster bolt is located through a hole in the adjuster bracket and threaded into the threaded receiver. An adjuster lock-down nut and fasteners through the adjuster plate slots keep the adjuster plate in the selected position. The dampers are connected to the rear damper mounting bracket by conventional means. By selectively threading the adjuster bolt into or out of the threaded receiver, the ride height of the motorcycle frame can be carefully controlled. Also, the alignment between the main frame and the swing arm can be carefully adjusted.

Apparatus for treating potable water to remove odorous sulfur compounds therefrom is disclosed. The apparatus comprises a treating tank, a fogging nozzle, means for directing water to be treated through the fogging nozzle and into the treating tank, means for injecting compressed air into the water directed through the fogging nozzle, a filter vessel, and a de-aerating vessel. The compressed air injected into the water that is directed through the fogging nozzle is at a pressure sufficiently high that minus 100 micron water droplets leave the fogging nozzle. Air, most of the sulfur compounds present in the water and some entrained water are ultimately discharged from the treating tank. The means for directing the water to be treated through the fogging nozzle is controlled to maintain a predetermined water level in the treating tank. The filter vessel contains a bed of a filter medium which forms a loose bond with the remaining H.sub.2 S in the filter vessel. The apparatus also includes means for directing water from the treating tank through the filter bed and into the de-aerating vessel, means for injecting air into water withdrawn from the treating tank before it flows through the filter bed, and means for venting gases from the de-aerating tank.

An illuminated safety helmet assembly for indicating turns and braking includes a shell that is substantially complementary to a helmet. The helmet is configured to couple to a head of a user and the shell is configured to couple to the helmet. A first power module is coupled to the shell. A first light, positioned on a right side of the shell, and a second light, positioned on a left side of the shell, are coupled proximate to a back of the shell. A third light is coupled to and is centrally positioned on the back of the shell. A controller, coupled to the shell, is operationally coupled to the first power module, the first light, the second light, and the third light. The controller is configured to selectively operationally couple the first light, the second light, and the third light to the first power module.

A convertible child carrier is provided comprising a pair of opposing central hub members having telescopic rear legs pivotally attached the hub members at a first end. Each of the legs has a pivotable wheel affixed to a second end. The child carrier further includes a yoke member generally defining an arch-like shape that is also pivotally attached to both of the pair of hub members. An additional wheel is affixed a central section of the yoke member. The child carrier further includes a handle member pivotally attached to each of the hub members, a seating portion disposed between the distal ends of the yoke member, and a storage portion affixed to the handle member defining an internal storage cavity. The rear legs, the yoke member, and the handle member each may pivot to a stowed configuration such that the storage portion encompasses the members within the storage cavity.

A deadbolt mechanism including a lock out mechanism that functions to disable the operation of the deadbolt from at least one side of the deadbolt mechanism. The deadbolt mechanism includes a deadbolt, key cylinder, housing, turn knob and a shaft that connects the key cylinder and turn knob. To place the deadbolt mechanism in lock out mode, a release mechanism is actuated and the turn knob is pulled outward away from the door. By pulling the knob outward, the shaft engages a portion of the housing which prevents rotation of the shaft and thereby prevents movement of the deadbolt from the lock-out position.

Systems and methods of providing remote, real-time computer-facilitated instruction, interaction, testing, and assessment to a plurality of users or participants. The system includes a system (e.g., a server) for shaping and directing a learning or decision-making environment. The shaping/directing system selectively provides content to users based on responses from the users to create a user-directed and generated learning or decision-making experience. The users connect to the shaping/directing system through a plurality of respective, user-controlled client devices. Each respective client device includes an input device (e.g., a pointing device) and an output device (e.g., a display). The output device communicates portions of the content, including decision points, to the respective user. The input device receives responses from the respective user. The responses reply to the respective decision points.

A 4-cycle, 4-cylinder internal combustion engine which comprises a hollow cylindrical engine casing with only three moving parts, a single rotary piston wall and two rotatable valve cylinders. A hollow cylindrical motor casing is divided in half vertically by an internal dividing wall. A single oil-cooled rotary piston wall is pivotally attached to the center of the internal dividing wall to create four variable size cylinders as the rotary piston wall pivots back and forth with the firing of the four spark plugs each firing into one of the four cylinders.

A deadbolt mechanism including a lock out mechanism that functions to disable the operation of the deadbolt from at least one side of the deadbolt mechanism. The deadbolt mechanism includes a deadbolt, key cylinder, housing, turn knob and a shaft that connects the key cylinder and turn knob. To place the deadbolt mechanism in lock out mode, the turn knob is moved to the locked positioned and then pulled outward away from the door. By pulling the knob outward, the shaft engages a portion of the housing which prevents rotation of the shaft and thereby prevents movement of the deadbolt from the locked position.
