摘要:
Apparatus to detect droplets and methods for detecting droplets are described. The apparatus comprise a light emitter and a light detector. The light emitter is to emit light along an optical axis, the light having a spatial intensity distribution profile with a peak that is non-coincident with the optical axis. The light detector is located relative to the light emitter such that, in use, the peak of the spatial intensity distribution profile is incident on the light detector.

Embodiments of the present invention allow a user to locate lost items on a global basis without the need for a paired transmitter device. The missing item may be located using a call in phone number, SMS message, or through a web-based or mobile device application. The missing item (or item subject to being lost) is affixed with a light or sound emitting element that receives a locator signal triggered by a call to the aforementioned phone number, SMS message, or web/mobile instruction.

A method for determining real time liquid phase flow rate from a biphase stream includes the steps of: providing a stream of a biphase fluid including a gas phase having a known gas density and a liquid phase having a known liquid density; providing a separator having a known volume gradient corresponding to liquid level in the separator; feeding the stream to the separator so as to provide a separated liquid phase containing a portion or the gas phase as entrapped gas and a separated free gas phase in the separator; measuring density of the separated liquid phase; measuring change in level over time of the separated liquid phase in the separator; and determining a liquid phase flow rate from the change in level over time, the separated liquid phase density, the known gas density and the known liquid density.

There is disclosed a housing including a plurality of compartments for housing a plurality of LEDs or photo detectors. Each compartment has a number of control pads projecting inwardly and a number of protrusions. The control pads are configured to provide a contact surface for the LEDs or photo detectors to control the alignment and position of each of the plurality of LEDs or photodiodes within each of the plurality of compartments. Each of the protrusions urges each of the plurality of LEDs or photodiodes against the respective control pads to control the alignment of the LEDs or photodiodes in the housing. A detector array including a casing, an LED housing and a photodiode housing is also disclosed.

In some examples, a printhead drop detector comprises a plurality of drop detection units. Each drop detection unit may comprise a radiation source and radiation detector and may be to detect a drop passing through a sampling volume between the radiation source and the radiation detector. A radiation detector of a first drop detection unit and a radiation source of a second drop detection unit is arranged on a first side of the sampling volume; and a radiation source of the first drop detection unit and a radiation detector of the second drop detection unit is arranged on the second side of the sampling volume.

The invention relates to a threaded device (7) embodied in the form of an anti-twisting stop which is rotatably connected to a traction-pressure rod. The inventive device comprises two oppositely located ratchet devices which are connected by a body enabling to stop the traction-pressure rod in several rotational positions with a predetermined locking force and, afterwards, to release it each time. Said threaded device (7) facilitates the mounting of the traction-pressure rod by the fact that the twisting should not be locked by additional handling, thereby making it possible to carry out a fine adjustment without additional measures. The ratchet device (4) comprises, for example, two ratchet elements (10, 11) provided with one or several catch lugs (12) or a metal or plastic ring part on one side and a gear rim on the other side. In addition, said threaded device can be provided with a spring element and a second anti-noise threaded device.
