  • Patent number: 11554235
    Abstract: A trap bowl is provided to accumulate liquid droplets from a filter, as a liquid content. The trap bowl includes a transparent vertical prism. The transparent vertical prism includes a face that forms a vertical transparent surface facing against a content of the section. The face can provide a first angle of total reflection when content of the section is a type of gas, and a second angle of total reflection when the content of the section is the liquid content. A light source may emit a light beam incident on the face at an angle of incidence. The angle of incidence results in reflection of the light beam, striking the light receiver, when the face has the first angle of total reflection, and results in refraction of the light beam, missing the light receiver, when the face has the second angle of total reflection.

  • Patent number: 11529471
    Abstract: A sliding cover for a liquid delivery device, such as a cap (100) for a pen injector (200), incorporates a set of sensors including an optical sensor (110) with an output which changes during uncapping or capping motions on passing of a plunger (220) of the pen injector. This output is used together with a position sensor (120) to determine the position of the plunger along a cylinder (210) of the liquid delivery device. By monitoring changes in the plunger position, the quantity of dosages delivered by the liquid delivery device can be determined, displayed, stored and/or transmitted to an external device for further data processing or storage. Preferred implementations of the invention employ optical sensors with a converging beam (115), and/or position sensors employing linear potentiometer strips (132).
