Factors That Can Influence the Performance of a Projected Capacitive Touchscreen

The accuracy of a touch screen device is crucial in different settings. A screen that does not read or respond to touch accurately can cause a variety of problems. For one, a device may register the wrong commands. Imagine a medical testing lab where the panel computer does not register accurately. Such a situation may lead to false tests; and consequently, incorrect diagnoses.

The same applies to operating machinery. Wrong commands can cause injuries or other damages. An inaccurate touchscreen monitor wastes a lot of time, which impacts productivity. Inaccuracy when operating a touchscreen display can lead to bad data and that has serious implications.

Hand Positioning and User Interface

The hand positioning is one of the factors that influence the performance of a touchscreen monitor. The centre of a screen is said to be the most accurate part. Moving fingers to the right or left side of a display may reduce its sensitivity. The user interface will also impact performance. Varying touch screen technologies require different stimuli to operate. For example, a projected capacitive touchscreen monitor only requires a simple touch and it registers a signal. A resistive touch screen, however, needs pressure on the display for the same results.

Haptic Systems

Some modern touchscreen monitors have haptic systems that influence performance. Integrating a haptic system in a touchscreen device allows the user to feel the vibrations of tactile input. Input has improved accuracy when a user can feel every single touch. The systems also make eye-hand coordination tasks easier.

Gloved or Bare Hands

Touchscreen devices can be used with bare or gloved hands, but it will depend on the technology. Resistive touch screens allow the use of gloved hand because they don’t interfere with the pressure. Gloved hands, however, interfere with input on a capacitive display because there is no electrical charge passing through the gloves;however,some types of gloves are designed to act as conductors, making them usable on a projected capacitive touchscreen.

How to Choose Between Sealed and Unsealed Panel PCs for Your Business

Panel PCs come in many forms. Chief among these are sealed and unsealed panel PCs. An unsealed PPC is often more affordable, but a sealed PPC is just that: a computer with no openings for matter or air to enter or leave.

Greater, Reliable Protection

Such PPCs usually have special fanless designs to address their cooling needs, and are generally built to a higher specification of internal durability and longevity (e.g. the disk drives in a sealed PPC are usually highly resistant to internal wear and tear). All of this helps create a computer that can function in a wide variety of situations, without inviting dangerous particular matter inside or sacrificing dependability.

Sealed Panel PCs Versus Particles

Particular matter varies widely in nature, but exists in many different settings. Large-scale indoor construction or welding can create a large amount of dust or heat. A restaurant setting is full of food particles, while a meat processing area might have a large amount of salt being moved and used within it. In all of these cases, a sealed Panel PC is far more resistant, perhaps even immune, to damage from these particles, which might otherwise enter an unsealed PPC.
Preventing Damage

On an individual basis many particles are not that harmful to a Panel PC. Dust will not interfere with a PPC’s components on its own. But it will clog the vents an unsealed PPC might use for heating, increasing the risk of damage. Other types of particles such as food particles can cause more immediate damage and malfunctioning, making sealed PPCs particularly important for non-dust particle evasion.

Temperature and How It Affects an Industrial Computer

Computers need to operate at a certain temperature range for effectiveness. One of the common causes of computer damage is temperature changes. While operating, a computer can experience an increase in temperature, which impacts the internal components. Computer parts such as the CPU and GPU generate heat when they carry out their respective functions. The heat generated also depends on the functions that a particular part is carrying out. If a computer is forced to conduct heavy workloads, then it will result in higher internal temperatures.

Impact of Temperature Changes

The changes in temperature will affect a computer differently. When a machine overheats, the cooling system commands components to slow down. Hard drives are particularly susceptible to changes in temperature and can get easily damaged. If a computer is not able to cool itself, then it may turn off if the heat is too much. Keeping a machine at ideal room temperatures is vital. In the case of lower environmental temperatures, condensation may form inside, leading to water-damaged parts. Turning on a computer that has been in cold temperatures can cause components to break due to expansion.

Controlling Temperature

One way of controlling temperatures in a computer is through the use of a fan. PCs have built-in fans that run systematically to prevent overheating of components. It is possible to get external fan controllers to regulate how the fan cycles. A user can also monitor the room temperature when operating a computer to ensure that it is at an ideal level.

Industrial Computers and Temperature Control

 Computers in industrial settings are exposed to a wide range of temperature changes but they are built for it. Firstly, the internal components of an industrial computer are designed to handle extreme temperatures. Industrial PCs come with temperature ratings to indicate what degrees of hotness or coldness they can handle. Manufacturers have also found ways to make casings that cater to temperature changes. An industrial computer housing allows excessive heat to dissipate, thereby preventing overheating. On the other hand, computers used in extremely cold environments can have onboard screen or internal heaters.
