The altitude of the location is 3, meters 12, feet.
A chamber is configured to enclose an input device such as a keyboard and is configured to be switched between an open and a closed state.
A drive unit may be provided to switch the chamber between 07.06 severe weather writing assignment. In an embodiment, the drive unit may include a motor. A sensor provides a signal to a controller when the chamber is the closed state and the controller actuates a UV light.
In an embodiment, the controller actuates the drive unit and the UV light in response to a trigger. In an embodiment, the trigger may be provided from a change in state in a computer coupled to the input device.
Individuals regularly enter and manipulate data on computer system and the computer has provided a substantial increase in productively.
Typically, most computer input is handled by a user touching some input device such as a mouse or keypad or touch screen in order to input or manipulate data. While this is effective with respect to working with the data, potential issues exist with the use of touch-based input devices.
Computer input devices are often touched by many people and therefore can allow the spread of bacteria and germs from one user to the next user. While this situation is problematic in normal office settings, in health care settings the situation can become more severe.
A caregiver may treat a first patient and then enter comments into a computer system via an input device. If a second caregiver also uses the same input device and then treats a second patient, there is a possibility that any bacteria or virus left on the keyboard by the first caregiver will be passed onto the second caregiver and make its way to the second patient.
As can be appreciated, this can be life threatening when dealing with highly infectious diseases, especially if the disease poses a serious health concern to the second patient.
While input devices can be sterilized by being wiped with a cloth containing a disinfectant therein, this approach has drawbacks. Therefore, improvements to how input devices are sterilized would be useful.
A chamber is provided for sterilizing the input device and includes a UV light.
The chamber may be switch between an open and a closed state by a drive unit. A sensor is provided to detect when the chamber is in the closed state.
A controller is coupled to the sensor and may be configured to cause the drive unit to switch the chamber between positions in response to a trigger and may be configured to actuate the UV light in response to a signal received from the sensor.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
An expanded portion illustrate ultraviolet UV light in is also provided, with UV-A light extending between and nanometers, UV-B light extending between and nanometers and UV-C light being less than nanometers.
As a rule, the smaller the wavelength the more power the wave has. While the sun emits wavelengths across the UV spectrum, the atmosphere substantially blocks wavelengths below about nanometers, thus vast majority of UV light that people are exposed to is UV-A light.
As is known, DNA consists of the molecules adenine, cytosine, guanine and thymine and the combination of these molecules provide the genetic information for a cell's offspring. Exposing cells to UV-C light causes adjacent thymine molecules in the cell to join.
The joining of the adjacent thymine molecules changes the DNA of the cell and prevents the cell from replicating and therefore makes it harmless. While all UV-C light tends to have a germicidal effect, DNA absorption peaks at about nanometers and at about nanometers thus UV light at or near these wavelengths is more effective as a sterilizing agent.
Thus, commercially available standard low pressure mercury-vapor lamps that emit UV light at about nanometers are suitable for use in sterilizing surfaces.
Because of UV-C light's germicidal effects, health agencies that work with infectious diseases have used UV-C light to disinfect surfaces.
However, care must be taken as exposure to UV-C is undesirable for individuals. A chamber is provided that may enclose an input device such as a keyboard and one or more UV lights 40 may be placed inside the chamber It should be noted that other input devices such as a mouse or touch pad or a lap-top or Tablet PC may be placed in the chamberthus the depicted keyboard is merely an exemplary embodiment.
A controller 20 is configured to actuate a UV light 40 when a signal is received from a sensor The sensor 30 is configured to provide the signal when the chamber is closed and the UV-C light may be safely applied. A drive unit 50 may be coupled to the controller 20 and may include a motor 55 that is responsive to an actuation from the controller The process of closing the door may actuate the sensor Jul 06, · This position is a Testing Designated Position (TDP).
