Abstract: The present invention relates to a portable device which analyzes cervical tissue using two simultaneous measurements, namely an electrical measurement and an optical measurement. The aforementioned device examines different areas of cervical tissue, taking electrical measurements from same in different frequency ranges and optical measurements in three different wavelengths. Once the measurements have been obtained, they are processed by a configurable device or microcontroller in accordance with mathematical formulae obtained from multiple measurements taken from healthy and cancerous tissues. Three possible responses can be obtained from the processing of the measurements: healthy tissue, cancerous tissue or the presence of human papilloma virus. The inventive device can be used as a self-detection device since it is equipped with an attachment for positioning same upon detection of proximity to the cervix in order to take a correct measurement.

Abstract: The disclosure is directed to a minimally-invasive diagnostic device for Papanicolaou testing and for an alternative examination method for taking a cell sample. The portable device analyzes cervical tissue using simultaneous electrical and optical measurements. The device examines different areas of cervical tissue, taking electrical measurements in different frequency ranges and optical measurements in three different wavelengths. Once obtained, the measurements are processed in accordance with mathematical formulae obtained from multiple measurements of healthy and cancerous tissues. Three possible responses can be obtained: healthy tissue, cancerous tissue, or the presence of human papilloma virus. A device attachment permits use of the device for self-detection after determining proximity to the cervix, and also includes an accessory for performing the alternative method of taking a cell sample for laboratory analysis to obtain an immediate response for use by the user or another person.

Abstract: This invention describes a lighting device with low energy consumption, which is made up of light emitting diodes known by the English acronym of LEDs, that use the technique known as “scanning”; with the purpose of reducing the consumption of energy required for lighting. Said scanning is performed by an efficient circuit that determines the sequence and time required for the activation of each LED or group of LEDs. The invention does not limit itself to only using LEDs, other types of elements for control may be used that may be sequenced without altering its operation or useful life. In this case, the speed that may support the LEDs is taken advantage of and that is higher than can be seen by the human eye, where each LED or group of LEDs are turned on and off at a frequency that is imperceptible by the human eye. Solutions are also presented to reduce the voltage by electronic means and rectification of the current using the LEDs themselves that intervene in the lighting.
