Patent number: 11850024Abstract: Embodiments of the present disclosure include a photodiode that can detect optical radiation at a broad range of wavelengths. The photodiode can be used as a detector of a non-invasive sensor, which can be used for measuring physiological parameters of a monitored patient. The photodiode can be part of an integrated semiconductor structure that generates a detector signal responsive to optical radiation at both visible and infrared wavelengths incident on the photodiode. The photodiode can include a layer that forms part of an external surface of the photodiode, which is disposed to receive the optical radiation incident on the photodiode and pass the optical radiation to one or more other layers of the photodiode.Type: GrantFiled: August 4, 2021Date of Patent: December 26, 2023Assignee: MASIMO SEMICONDUCTOR, INC.Inventors: Steven J. Wojtczuk, Xuebing Zhang, William J. MacNeish

Patent number: 9847749Abstract: Solar panels located on residential roofs can be unsightly in some cases. A swimming pool solar power generator can locate solar panels in or around the sides and/or bottoms of a swimming pool in a manner so as to create electricity from the sun without creating an eyesore. In an embodiment, a pool solar power generator includes a solar cell module disposed in a portion of a swimming pool. The solar cell module can include solar cells and be submerged under water held by the swimming pool. The solar cell module can convert sunlight incident on the solar cells to electricity and transmit the electricity for use at a location external to the swimming pool.Type: GrantFiled: September 10, 2015Date of Patent: December 19, 2017Assignee: MASIMO SEMICONDUCTOR, INC.Inventors: Massi Joe E. Kiani, Steven J. Wojtczuk, Brad M. Siskavich
