Executive Summary The Saluki Engineering Company (SEC) has designed and completed a functioning prototype of a Clicker Activated Bicycle Lock (CABL) at the request of client Frances Harackiewicz. When designing; size, weight, durability, and safety were taken into account. The CABL is small, lightweight, and has a removable locking mechanism for safety. The CABL has 7 subsystems that were to be designed and constructed.

G-Project Description (CW) G-1 Introduction People are always looking for alternative modes of energy including alternative modes of transportation. Bicycles are an affordable alternative to gas powered vehicles, especially if you live in a city; therefore many people have chosen bikes as a way to transport themselves. Due to the increase in bicycle use, bicycle theft has also become an issue.
bicycle is theft actually occurs. The power system distributes power through each subsystem except for tracking and allows for the modulation of signals into logical data. The accelerometer sensor sends logical signals to the control that tells to activate the alarm if movement occurs when the CABL is in an armed state. The locking mechanism consists of a locking cylinder and a cylinder manufactured with a door lock actuator (DLA) to electronically unlock the cable.

G-4 Implementation schedule In order to construct a model approximately five weeks would be needed. The first week would be to finish designing any changes to the product and ordering parts to begin construction. Once parts are acquired construction would begin in week two starting with the locking mechanism. The third week would consist of construction of the control circuit and testing using logical inputs provided from a DIP switch.
2-3 days for final construction 2-3 days for testing of finished product 1-2 days for trouble shooting finished product G-5 Options considered Many different design implementations were considered for the subsystems. After much research and comparing designs against products found on the market a final design was decided upon.
G-6 Summary of fault analysis There were issues that arose during testing that have need of fixing; these issues pertaining to the locking mechanism, the accelerometer, and the power system. There is a safety concern with the locking mechanism that is partly taken care of by the removable cable.
The final suggested option would be to use variable voltage regulators in stages to down step the voltage and allow each regulator to dissipate a smaller amount of power. These regulators will still produce heat, but the regulators will not over heat due to the minimized power dissipation on each stage. The only complication is that the total power dissipation of the system will increase and the battery may not stay charged as long during activation.
are that if the bicycle location does not have a street address is may only be found on the map, and that if the bicycle is not in an area that has cellular service it will not function. The Zoombak tracker was compared to a TK102 tracker.

signals from the RF receiver when user input is given in the form of a voltage and runs it through a resistor to supply logic data to the control circuit. It also receives voltage from the control circuit through a transistor to turn on a 12 V relay that supplies power to sound the alarm. This is required due to the low current output from the PROM not being able to energize the relay. Power is stored within a rechargeable battery pack.
P-2 Explanation of engineering drawing A simplified version of the power system was drawn using Expresspcb. This program allows for the drawing and labeling of a complete circuit including sizes for production of a dual sided, copper traced, printed circuit board. The green traces of the circuit board are the bottom side of the board; these traces carry the positive voltage through to each component and allow for signal processing of the signals from the RF receiver.

the question for power concerns the circuit was simplified as much as possible. The FSM was simplified to 3 states named "Disarmed" (or 0), "Armed" (or 1), and "Active" (or 2) to describe their functionality. A state diagram can be found in figure C-1 in appendix C. "One-Hot" encoding was used allowing each state to have its own flip-flop in the FSM. This allowed the system to catch a glitch and handle it much easier than classical encoding.
used for timing. The FSM and counter have a common clock signal with a 1 kHz frequency. The control has 3 external inputs: Arm, Disarm, and the Accelerometer output. It also has 2 outputs: Alarm enable and a reset for the accelerometer circuit. Due to the many different states allowable with a PROM device, the device has to be programmed using a long truth table. We have provided a logically simplified truth table for programming the PROM to work as the combinational logic of the finite state machine.
A Alarm (CW) A-1 Technical Summary The alarm subsystem was a simple audible alarm that was decided upon taking into account the need for the alarm to be heard through material and from a distance. The threshold of pain is taken into account too so a dB level of around 90 was decided upon. A 12VDC piezo buzzer was decided upon giving us a dB level of 87 with a slow pulsing alarm when voltage is applied to it.
design was that of a clamp that would be part of one container, holding all the subsystems, which would have the ability to be engaged and disengaged electronically. This idea was discarded due to the high amount of power required for the solenoids that it would require as well as the safety concerns presented if the lock accidently engaged while riding.
L-2 Safety Issues and Solution A major issue with the locking mechanism is safety. Because there is no other way to remove the cable from the lock housing the cable would be removed using the key from the cylinder and then wound around the bottle and secured back into the key cylinder. This presents the concern that the cable may get stuck in, or wrapped up in either the spokes of the tires or the sprockets of the bicycle.
S Accelerometer Circuit S-1 Technical Summary The accelerometer circuit for the CABL can detect acceleration of half of a G- Force. The circuit works by taking the signals produced by our Parallax mimsic dual axis accelerometer and converting them to logical ones and zeros to be given to the control. The Accelerometer circuit and the control circuit work together to accomplish this task. The two signals correspond to acceleration along one of the axes.

Applying a negative pulse simultaneously to the reset terminal (4) and the trigger terminal (2) during the timing cycle discharges CT and causes the timing cycle to restart. Momentarily closing only the reset switch during the timing interval discharges CT, but the timing cycle does not restart.

Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.

High Security Protocol ‘Easy Learn’ Feature Easy Installation Via Screw Terminals. Up to 7 Transmitters per System Relay Outputs 5A @ 230Vac Momentary or Latching Outputs Robust Enclosure FCC / CE Compliant Range up to 100 Metres Description A versatile general purpose remote control, which can be used for controlling many different applications. The system utilises the highly secure Keeloq code hopping protocol to ensure reliable operation.
c. After the LED stops flashing, press the short the LRN pins again to select the next relay channel d. Repeat step c until the required output relay is selected. 2. Press the button on the transmitter you want to learn to the relay output. 3. The Learn LED will then illuminate, press the same transmitter button again. 4. The Learn LED will then flash to indicate learning is complete. 5. To test the operation, press the transmitter button again and you will hear the relay ‘click’ as it operates.
