18 Awe-inspiring Modifications to a Movable Cubicle

Some people believe that no matter how many changes that a movable cubicle will undergo, it will never change the fact that it can only transport and store materials without maintaining their qualities. This perception isn’t true, especially if the cubicle has one or more of the these 18 modifications:

1. Shelves

Movable CubicleThey keep dry and refrigerated materials off the floor. Shelves keep those materials organized in a movable cubicle. Easier accessibility to materials and greater air circulation will occur because materials are not stacked on top of one another. Meshed shelves can accommodate spill from perishable drinks. Heavy duty shelves can lift plenty or heavy materials for a long time. Lightweight shelves can raise light or few items. However, they can function as heavy duty shelves for a short time.

2. Workbenches

These tables are where packing and unpacking of shelved items are done. Workbenches with mesh allow spillage from liquid or wet goods. These tables can either be fixed or moved in a movable cubicle from one area to another.

3. Alarm system

This system produces an audible signal that can alert people of a possible break-in and theft. It usually happens after a thief is able to unlock the lock.

4. HVAC system

This system includes heating, ventilation, and air conditioning to control internal temperature. It is typically used for cubicles that are divided into multiple sections. Residential applications aren’t suitable for this system.

5. Lock box

This simple lock hides and protects the padlock from being cut by bolt cutters. It’s welded to the cubicle’s doors for easy access.

6. Window

This modification allows people to check inside the movable cubicle for missing items without going inside.

7. Personnel door

This door is commonly used for residential and industrial applications because of its resemblance to an ordinary door. An industrial personnel door can secure stored items because it is constructed out of steel. A residential personnel door is cheaper because it is manufactured from wood.

8. LED light

This light only needs to be attached to a small battery for it to illuminate the cubicle’s interior. It is suitable for cubicles that don’t have access to electricity or are placed in isolated areas.

9. Flood light

This light brightens the area surrounding the cubicle. Some cubicles have flood lights that are mounted with alarm systems.

10. Receptacles

These lights require 110 volts of energy to function properly. They usually come with two or four power outlets. Receptacles can be shown or flush mounted on the cubicle’s interior wall panels.

11. Refrigeration

This allows the cubicle to electronically control interior cold temperatures to store perishable goods.

12. Rooftop turbine vents

These are the cheapest vents that can be mounted on the cubicle’s roof. They don’t require power to function. They control the amount of airflow in the cubicle.

13. Overhead light

This light contains a 2-bulb florescent fixture. 20-feet cubicles typically have two overhead lights. 40-feet cubicles commonly have four overhead lights.

14. Skylight

This illuminates the cubicle’s interior from the ceiling. It gets its light source from the sun.

15. Side doors

These doors allow items with larger widths to be loaded and unloaded in the cubicle.

16. Fiberglass insulation

This contains a plywood-framed or a wood-framed interior with a fiberglass insulation value of R-13. Its surface is either fireproof or waterproof and it is easy to clean.

17. Partitions

They separate items from other compartments that will be used for other applications. For example, one part of the cubicle will be used for storing office supplies and the other part will be used as an office workspace.

18. Security bars

These bars prevent thieves from entering the cubicle through the window or skylight.These are 18 modifications that a movable cubicle can have.

Printed Circuit Boards: A Brief History and Components

Printed circuit boards, also known as printed wiring boards or printed wiring cards, are parts of an electronic device which connect its internal components together to create a circuit, which makes the whole device function. This is commonly seen in computers but can also be found in any other device that uses electricity. To find out what a circuit board looks like, all you just need to do is look at a computer’s motherboard.

printed circuit boardsWhen printed circuit boards were created, it had solved the issue of complex circuitry with electronic components. To find out when it was first used, it can be stated that it started around the 1900’s. Back in 1925, Charles Ducan was able to submit a patent for an electronic pattern that was printed onto an insulated board. It was in 1943 that Paul Eisler was able to build one of the first circuit boards.

Before printed circuit boards were widely used, “point-to-point construction” was the technology found in contemporary electronic devices. This is where each component of an electronic device was painstakingly connected with wires from one part to another. These devices were bulky and would easily breakdown. When repairing such a device back then, it would call for replacing either the connecting sockets for each component, or replacing the wire connecting them, or both. Wires were sensitive that time and the insulation for each wire was not as sturdy compared to the wires now. Some of the first devices that used circuit boards were the gramophones and radios built during the 1920’s.

Manufacturers would use wood as the board and they would rivet the electronic components in place on one side and then run the wires on the other side of the board. During the 1950’s and 1960’s, the use of was then known and a few patents were filed to further improve their efficiency. With the initial designs, the circuits were placed only on one side of the board, but eventually, multilayer boards, or a board with more than one printed circuit on it, were created.

A typical circuit board would have a hole in it where an electronic component would fit in place. This is called a Plated-Through Hole. Once the component is in place, it is then soldered either by hand or by machine to secure it. Each hole would have a copper ring around it, called an annular ring.

When two circuit boards need to be connected to each other, a section of the board is set where part of the copper pattern is exposed. These are called “fingers” and are always located at the edge of the board. They would then be pushed into connectors that are installed in the other circuit board, just like how components of a computer are attached to a motherboard. If the circuit board needs to be cut in a certain place, manufacturers would place a V-score or a “mouse bite” on the board. These are partial cuts on the board so that anyone can snap off one part of the board cleanly and easily.

A solder mask is placed over the circuit board to protect the copper paths that are already printed onto it. The solder masks are what gives the circuit boards its typical green colour, though some boards may be red. The solder mask also protects the board from accidental solder jumps, or when an extra solder suddenly connect two copper circuits accidentally.

For some components that cannot be installed through holes, some boards would have a slot put on the board itself. This is typically used if the connecting part is not rounded. A silkscreen layer is used to give a label to each part of the board. The labels are usually white so that they can easily be read.
