Abstract: A wrist-wearable electronic device comprising first and second light emitting elements, a sensor, and a processor. The processor is configured to transmit a first command to the first light emitting element in response to the wrist-wearable device reaching a forward position relative to a user based on data received from the sensor and transmit a second command to the second light emitting element in response to the wrist-wearable device reaching a rearward position relative to the user based on the data from the sensor.

Abstract: A sonar array system comprises a plurality of sonar arrays and a sonar signal processor. Each sonar array is configured to receive transmit electronic signals and transmit corresponding sonar beams in a forward direction and a downward direction. Each sonar array includes a plurality of groups of sonar transducer elements, with each group including at least a first sonar transducer element and a second sonar transducer element. The sonar signal processor is configured to communicate a plurality of transmit electronic signals to the sonar arrays. The transmit electronic signals include a first transmit electronic signal including a periodic waveform having a first phase and a second transmit electronic signal including a periodic waveform having a second phase. A distribution of power between the sonar beams transmitted in the forward direction and in the downward direction varies according to a difference in the first phase and the second phase.

The processing element is configured to receive a first sonar electronic signal from a first sonar transducer, receive a second sonar electronic signal from a second sonar transducer, generate data for a first underwater image stream from the first sonar electronic signal and a second underwater image stream from the second sonar electronic signal. The display is configured to show at least one of the first underwater image stream having a first view derived from reflections of a first sonar beam, the second underwater image stream having a second view derived from reflections of a second sonar beam, and an indication of a position of the first sonar beam relative to the second sonar beam.

Abstract: Autoland systems and processes for landing an aircraft without pilot intervention are described. In implementations, the autoland system includes a memory operable to store one or more modules and at least one processor coupled to the memory. The processor is operable to execute the one or more modules to identify a plurality of potential destinations for an aircraft; calculate a merit for each potential destination identified; select a destination based upon the merit; and create a route from a current position of the aircraft to an approach fix associated with the destination that accounts for the terrain characteristic(s) and/or obstacle characteristic(s).

Abstract: An apparatus is disclosed for determining validity of a measured in-blood percentage of oxygenated hemoglobin. The apparatus has multiple pulse oximetry channels having at least three light sources of at least three distinct wavelengths, which are detected and converted to digital signals. The light sources are selectively activated, and two or more estimated in-blood percentages of oxygenated hemoglobin are calculated. It is determined whether a signal quality associated with the calculated in-blood percentages exceeds a predetermined accuracy threshold, and an associated validity indication is provided.

In implementations, the autoland system includes a memory operable to store one or more modules and at least one processor coupled to the memory. The processor is operable to execute the one or more modules to identify a plurality of potential destinations for an aircraft.

Abstract: An automated avionics system for determining a modified descent path of an aircraft includes a memory operable to store a database of flight information related to a flight plan and a processor operably coupled with the memory. The processor is operable to receive an indication to initiate descent of the aircraft associated with a position of the aircraft, receive information related to the flight plan from the database, and based on the information received, perform modifications to the path of descent. The processor is further operable to, based on a comparison of an original position of descent and the indicated position, determine a modified position of descent for the aircraft and calculate a modified path of descent, the modified path of descent complying with the of altitude constraint(s) of the flight plan.

Abstract: A removable camera lens attachment has at least two optical elements, wherein the at least two optical elements are aligned to share an optical axis with a prime lens of the camera. The lens attachment has at least two curved surfaces. The at least two optical elements have a first surface that is conditioned to reflect a first portion of the incident light away from the image plane as reflected stray light and a second surface that is conditioned to reflect a second portion of the reflected stray light back toward the image plane to form a ghost image on an image plane of the prime lens. The lens attachment alters the effective focal length of the prime lens by no more than 15%.

Abstract: A flight deck system for an aircraft includes a processor, a graphical interface for displaying flight-related information in the form of selectable items, a control interface for receiving a selection of the selectable items, and a non-transitory computer-readable storage medium for storing electronic representations of charts. The selectable items correspond to the electronic representations of charts, and the electronic representations of charts describe minima and associated conditional criteria for operating the aircraft (e.g., proximate to an airport). The processor is configured to arrange the selectable items, receive a selection of the selectable items, identify a corresponding one of the electronic representations of charts, receive a condition associated with the aircraft, compare the condition to the conditional criteria for operating the aircraft to identify an applicable one of the plurality of minima, and display the applicable one of the plurality of minima on the graphical interface.

Abstract: Disclosed are dual-light-source, high dimming-ratio avionics displays with digital light processing projector technology for rendering a visual display from generated light. The dual light sources are directed towards a beam splitter adapted to pass a substantial portion of the light from the first light source and to reflect a minority portion of the light from the second light source. An image is rendered at a substantially transparent, selectively reflective substrate adapted to reflect light of a range of visible wavelengths toward a viewer of the displays.
