  • Patent number: 11873980
    Abstract: A photocontrol, such as for an outdoor intelligent lighting fixture, may detect levels of ambient light at multiple sections of the photocontrol. The ambient light may be detected via multiple photosensors located at the photocontrol sections. In addition, the ambient light may be detected via multiple color filters (or sections of a color filter) located at the photocontrol sections. The photocontrol may determine an ambient light differential, such as an instant differential between light received at the multiple photocontrol sections at a particular time, or a temporal differential between light received at the multiple photocontrol sections across multiple times. Based on the ambient light differential, the photocontrol may identify triggering photosensor or triggering section that substantially align with a geographical orientation. The photocontrol may identify a lighting output profile. An output level of a lighting element may be modified based on the lighting output profile.

  • Patent number: 11402374
    Abstract: The invention relates to a method for the detection of target components that comprise label particles, for example magnetic particles (1). The method includes (a) collecting the target components at a binding surface (12, 112, 512) of a carrier (11, 111, 211, 311, 411, 511); (b) directing an input light beam (L1, L1a, L1b) into the carrier such that it is totally internally reflected in an investigation region (13, 313a, 313b) at the binding surface (12, 112, 512); and (c) determining the amount of light of an output light beam (L2, L2a, L2b) that comprises at least some of the totally internally reflected light. Evanescent light generated during the total internal reflection is affected (absorbed, scattered) by target components and/or label particles (1) at the binding surface (12) and will therefore be missing in the output light beam (L2). This can be used to determine the amount of target components at the binding surface (12) from the amount of light in the output light beam (L2, L2a, L2b).

  • Patent number: 11272983
    Abstract: Optical fibers for delivering laser energy inside the body are often tasked with traversing tortuous routes in accessing the target tissue or pathology, e.g. ureteroscopic laser lithotripsy. A common failure in such applications, known in the field as ‘fiber burn through’, has been known to injure patients and is a major cause of damage to ureteroscopes. Where irregular output that is produced at the start of a lasing interval passes through a fiber that is at or near the optical minimum bend limit, fail safe polymer claddings are damaged and can no longer contain even regular laser output in tight deflection. The invention disclosed provides a solution to premature fiber failure and collateral damage.

  • Patent number: 11002571
    Abstract: The present invention relates to a method of fabricating a nanowire connected to an optical fiber, the method comprising the steps of: a) filling a micropipette with a material solution to form a nanowire; b) coaxially aligning the micropipette with the optical fiber at one end of the optical fiber such that a longitudinal axis of the optical fiber and a longitudinal axis of the micropipette are aligned in a line; c) forming a meniscus of the material solution to form the nanowire in the coaxially aligned state; and d) fabricating the nanowire by evaporating a solvent from the material solution to form the nanowire while lifting the micropipette in a state in which the meniscus is formed, in a direction away from the optical fiber. The method further comprises a step of a step of controlling a shape of the distal end of the nanowire by irradiating a laser to the nanowire fabricated.

  • Patent number: 10982996
    Abstract: A proximity sensing device includes: a light source, a sensing unit, a light guide unit, and a window. The light source emits light, which is guided by the light guide unit to the window. The emitted light reflected by an object is received by the same window. The light guide unit includes a partial-transmissive-partial-reflective (PTPR) optical element, whereby the light emitted from the light source is reflected by the PTPR optical element, while the light reflected by the object passes through the PTPR optical element. There is only one window required.

  • Patent number: 10958061
    Abstract: A method includes detecting any light beam from 300 nm to 430 nm within the distribution system and, when this beam is detected, generating a signal indicating the presence of an internal arc inside the system; analyzing the characteristics of the light beam based on the signal and, if these characteristics meet required conditions for characterizing an internal arc fault, sending an internal arc fault signal, then; in the presence of an internal arc fault, attenuating its effects in the distribution system. Between the detecting and the analyzing, the visible and infrared portions of this beam are removed, these portions being likely to arise from ionized gases ejected by outlets of a low-voltage circuit breaker interrupting a short-circuit current. A protection device for carrying out this method includes a light detector associated with current-measuring sensors, and protection means including a main circuit breaker, a short-circuiter and a relay.

  • Patent number: 10953254
    Abstract: Disclosed herein is a system and process for monitoring and controlling fire suppression systems in commercial kitchens. Repeatedly various components of the fire suppression systems are tested for faults. When a fault is detected in a particular component, the fault is communicated through a communications module associated with the commercial kitchen via the internet to one or more remote servers. Upon receiving information indicating a particular fault, the one or more remote servers acts to alert interested parties of the default.

  • Patent number: 10906056
    Abstract: Among other things, a dispensing device and/or a refill container are provided. The dispensing device may comprise a dispenser component configured to dispense a refill material. A sensor component may be configured to identify an optical property (e.g., whether an optical brightener is present in the refill material) of the refill material. The dispensing device may evaluate the optical property against an optical profile to determine whether the refill material is a valid refill material (e.g., comprises the optical brightener) or an invalid refill material (e.g., does not comprise the optical brightener). Operation of the dispensing device may be enabled based upon the refill material being the valid refill material. If the refill material comprises the invalid refill material, then operation of the dispensing device may be disabled and/or a flush option (e.g., evacuating the invalid refill material from the dispensing device) may be activated.
