  • Marking and counting probe
    Patent number: 5995123
    Abstract: A marking and counting probe for use with a counter, e.g. a computer, comprises a tubular housing for holding a marking implement, such as a highlighter. One end of the tubular housing has an aperture through which the marking end of the marking implement extends. The other end of the housing is closed and has a switch which is activated by the marking implement when a certain activating pressure is applied to the switch by the marking implement. A resilient means, such as a spring within the switch, keeps the marking implement from activating the switch until the activating pressure is applied to the switch by pressing the marking end of the marking implement against a surface. The switch is connected to a counter whereby, when sufficient pressure is exerted on the switch by the marking implement to activate the switch, a count is recorded.

  • Marking and counting implement
    Patent number: 5442380
    Abstract: A marking and counting implement comprises a tubular housing for holding a marking implement, such as a highlighter. One end of the tubular housing has an aperture through which the marking end of the marking implement extends. The other end of the housing is closed and has a switch which is activated by the marking implement when a certain activating pressure is applied to the switch by the marking implement. Typically, a resilient means, such as a spring, keeps the marking implement from activating the switch until the activating pressure is applied to the switch by pressing the marking end of the marking implement against a surface. The switch is connected to a counter whereby, when sufficient pressure is exerted on the switch by the marking implement to activate the switch, a count is recorded. Thus, the marking and counting implement can be used for both marking and counting.
