Abstract: An active sheath for a recognition probe of a handheld cancer screening device, in which the conductors and circuits are applied on the surface of the sheath such as in the form of a flexible circuit made of a biocompatible material and a flexible conductor or a conductive ink in the surface of the disposable cover's tip without the need to embed the electrodes or other components inside the plastic cover.

Abstract: Disclosed is an energy collector system applicable to internal combustion engines. It may include: a) a collector of thermal energy from the exhaust gases; b) a thermal tank covered by helical tubes to gain heat by the exhaust gases; c) a heat exchanger; and d) an outer element capable of converting thermal energy into mechanical energy, such as a closed Brayton cycle turbine, a Stirling engine, a Rankine turbine or an open loop air motor for converting mechanical energy (coupling the difference in rpm) into electrical energy with an electrical generator. The thermal energy collector may be composed of a heat exchanger that collects energy from the exhaust gases. The electrical energy generated may be used for driving a hybrid vehicle. The thermal tank is capable of storing energy as heat, as well.

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: The invention relates to a flat solar collector comprising individual vacuum chambers. The invention is formed by two heads and a series of parallel tubes having high transmittance in the solar spectrum, which is disposed between said heads. The opposite side of the heads is provided with vacuum chambers which closure the connections of the conducting tubes. One of the vacuum chambers is characterized in that it is fitted with a vacuum valve at one end thereof. In addition, conducting tubes are disposed inside the aforementioned tubes having high transmittance in the solar spectrum and said conducting tubes are in turn connected to collector plates, all under vacuum conditions which minimize convection energy losses. When the conducting tubes are configured in series, the collector can raise the temperature of the working fluid to above 200° C. All of the above is performed in a novel, simple and economical manner.

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.
