Abstract

A system of a multi-rotor aircraft that capitalizes on the advantages of fixed wing elements combined with rotary wing structures. The fixed wing elements can help to generate lift once the aircraft is airborne and can thus reduce the need for larger lifting rotors which can allow for longer flight times and distances. Additionally, the systems disclosed herein take advantage of a partial in-wing configuration with a number of rotors to reduce the overall footprint of the vehicle while maintaining the flight efficiency that comes with combining features of fixed and rotary wing elements, and increasing operator safety by shrouding rotating parts. The unique configurations allow for a decoupling of the pitch, yaw and roll authority to reduce the complexity in control systems and improve the flight efficiency of the aircraft. Additional configurations implement the use of smaller thrust rotors that can be used to generate thrust as well as control yaw and thus counteract any remaining unbalanced torque.

An entertainment system generates a tone mark in response to a tone mark generating operation performed by a first player, move the tone mark toward a second player area, generates a tone mark in response to a tone mark generating operation performed by a second player, and moves the tone mark toward a first player area. When the tone mark generated by the second player arrives at the first player area, whether the first player performs a tone output operation is determined. When the tone mark generated by the first player arrives at the second player area, whether the second player performs a tone output operation is determined. Communication points are calculated based on the tone mark generating operation and the tone output operation by the first player and the tone mark generating operation and the tone output operation by the second player.

Abstract

An intraocular lens (IOL) has a small, central lens suspended within a pliable housing and, when the housing is filled with liquid, is coaxially aligned with a second small lens embedded in the wall of the housing. The suspension is on a dome- or other-shaped webbing attached to an inner circumference of the wall. When filled with liquid, forces squeezing or pulling the equator of the housing, as with ciliary muscles in the eye, adjust a distance between the lenses in order to adjust focus. Optional haptics may project from points on or above and below the equator. A recess in the posterior hemisphere of the housing can keep cell growth away from an optical axis of the lens system. A third small lens can be embedded in an opposite wall of the housing and coaxially aligned with the other lenses to form a three-lens, ultra-zoom system.

Abstract

Methods and devices for bias gyroscopes self-calibration are disclosed. The described teachings can be applied to inertial measurement units implementing one or more auxiliary Coriolis Vibratory Gyroscope (CVG) in conjunction with one or more primary gyroscopes. The auxiliary CVG, capable of mode-switching, enables continuous bias estimation for both its own operation and those of the primary gyroscopes without relying on external aiding sensors. The disclosed methods implement a Kalman filter for bias estimation and can update estimates either at every measurement time step or at mode switching intervals. By combining the good noise performance of primary gyroscopes with the bias stability improvement from the auxiliary CVG, an enhanced overall performance can be achieved.

Abstract

Lithium niobate (LiNbO3, LN) is a ferroelectric crystal of interest for integrated photonics owing to its large second-order optical nonlinearity and the ability to impart periodic poling via an external electric field. However, on-chip device performance based on thin-film lithium niobate (TFLN) is presently limited by propagation losses arising from surface roughness on the nano- and microscale. Atomic layer etching (ALE) can smooth these features and thereby increase photonic performance. In one embodiment disclosed herein, an isotropic ALE process for x-cut MgO-doped LN uses sequential exposures of H2 and SF6/Ar plasmas. We observed an etch rate of 1.59±0.02 nm/cycle with a synergy of 96.9%. ALE can be achieved with SF6/O2 or Cl2/BCl3 plasma exposures in place of the SF6/Ar plasma step with synergies of 99.5% and 91.5% respectively. The process decreased the sidewall surface roughness of TFLN waveguides etched by physical Ar+ milling by 30% without additional wet processing.

Abstract

Communication systems and methods in accordance with various embodiments of the invention utilize modulation on zeros. Carrier frequency offsets (CFO) can result in an unknown rotation of all zeros of a received signal's z-transform. Therefore, a binary MOCZ scheme (BMOCZ) can be utilized in which the modulated binary data is encoded using a cycling register code (e.g. CPC or ACPC), enabling receivers to determine cyclic shifts in the BMOCZ symbol remitting from a CFO. Receivers in accordance with several embodiments of the invention include decoders capable of decoding information bits from received discrete-time baseband signals by: estimating a timing offset for the received signal; determining a plurality of zeros of a z-transform of the received symbol; identifying zeros from the plurality of zeros that encode received bits by correcting fractional rotations resulting from the CFO; and decoding information bits based upon the received bits using a cycling register code.

Abstract

Bistable devices are constructed using a polynucleotide platform for the sensing of molecular events such as binding or conformational changes of target molecules. Uses include measurement of target concentration, measuring the effect of environmental condition (such as heat, light, or pH) on the target, or screening a library for molecules that bind the target or modulate its biological function. Devices comprise three regions: a top lid, bottom lid, and flexible linker or hinge between them. A device has an open configuration in which the top and bottom lid are separated, and a closed configuration they are bound close together. Binding domains or variations of the target molecule are fixed to a device so that when the molecular event occurs, the device switches from open to closed, or vice versa, which generates a signal. Devices carry DNA tags to enable separation of open and closed devices, as well as barcoding for multiplexed detection.

Abstract

A method to perform vision based navigation on a moving vehicle. An image processor receives reference images with associated depth information as base frames or search frames. 2D features are detected in base frames and tracked in subsequent search frames. A new base frame is triggered when a number of features or a spatial distribution fall under thresholds. A depth processor reconstructs the depth and 3D position of each of the 2D features. A track manager manages a feature list database mapping the 2D coordinates of each tracked 2D feature with the 3D coordinate of that feature. A state manager constructs a filter state vector with 15 error states propagated at an IMU rate and 6 additional error states corresponding to clones of pose states. A visual updater utilizes the tracked 2D feature coordinates to update the filter state vector. A filter forms residuals and corrects inertial error drift.
