Systems and methods for capturing and rendering hand skeletons over documents images for telepresence
In a telepresence scenario with remote users discussing a document or a slide, it can be difficult to follow which parts of the document are being discussed. One way to address this problem is to provide feedback by showing where the user's hand is pointing at on the document, which also enables more expressive gestural communication than a simple remote cursor. An important practical problem is how to transmit this remote feedback efficiently with high resolution document images. This is not possible with standard videoconferencing systems which have insufficient resolution. We propose a method based on using hand skeletons to provide the feedback. The skeleton can be captured using a depth camera or a webcam (with a deep network algorithm), and the small data can be transmitted at a high frame rate (without a video codec). |

Method for manufacturing ultra-dense LED projector using thinned gallium nitride
A small projector uses an ultra-dense array of gallium nitride (GaN) LEDs. However, epitaxial growth of GaN typically produces a GaN region that is Sum or thicker. To achieve high pixel density, the LEDs have small area, so the resulting LED structures are tall and skinny. This is undesirable because it makes further processing more difficult and has higher optical losses. As a result, it is beneficial to reduce the thickness of the GaN region. In one approach, a wafer with the GaN region on substrate is bonded to a backplane wafer containing LED driver circuits. The substrate is then separated from the GaN region, exposing a buffer layer of the GaN region. The GaN region is thinned and then patterned into individual LEDs. Typically, the buffer layer is removed entirely. |

Device for detecting algae concentration using first derivative of visible light absorbance
Monitoring and detection of algae in surface water and wastewater is of significant importance, yet there is currently no quick and simple method to achieve this. The present work illustrates a new method to determine the concentration of algae in water and wastewater samples using spectrophotometry, the first derivative of absorbance, and a smoothing technique applied to the first derivative of absorbance (e.g. Savitzky-Golay). The relationship between algal concentration and absorbance for three types of water samples (distilled, surface, and wastewater) was determined in the visible wavelength range, and the effect of using the first derivative of absorbance method on improving algal concentration detection limit was established. Using the first derivative of absorbance method improves algal detection limits, reduces the effect of background absorbance and the resolution of overlapping spectra. The presence of algae in water can cause a number of problems, and the method presented here can be used to effectively monitor algal concentration in various types of water samples and provide necessary information for decision making purposes. |

Deployable compliant mechanism
A mechanism is hereby disclosed that, when activated in the linear direction of its axis, will expand and contract radially. The novel nature of the device is that of compliant methods and materials used in its design. Compliant members, referred to as dyads, translate the motion and imply resistance in a single structure.

When these compliant dyads are combined in the novel configurations hereby disclosed, a device is created that expands (or contracts) in multiple directions from its primary axis of actuation. Furthermore, one or more actuation dyad sets could be arranged at various angles relative to the global vertical axis. The radial expansion/contraction can be 2D or 3D by adding more primary activation dyad sets. Such a device can be applied to many applications and industries. One such application is for gripping the inside of a tube or object for moving manually or in automation. The compliant nature of this device can be optimized to auto-adapt to the objects size and shape allowing for greater part variation and reduce manufacturing line change-over times. Other applications would include snap fit connections, spherical articulating joints, spinning cutting tools, speed limiting using friction and centrifugal force, braking rotational forces or transmitting it, automatic centering, expanding elastic bands in an assembly process, and stretching an opening for fitment. The design of this device is material friendly and can be made of plastic, composite and metals. It may be of a single monoform construction (created by molding, machining, or additive manufacturing) or made of multiple parts including pivots and different materials to achieve the desired articulation. |

Acoustic absorber for bass frequencies
An acoustic absorber includes a chamber formed from walls with a resistive portion providing the only communication between the chamber volume and ambient air. In some examples chamber walls enable selection or adjustment of chamber volume or resistive area, thereby altering the acoustic absorption spectrum below 250 Hz.

Density and heat capacity of the fibrous filler material results in the chamber volume exhibiting compressibility of air within the chamber, for at least acoustic frequencies up to about 50 Hz, that is larger than adiabatic compressibility of air. That larger compressibility results in an increased acoustic absorption coefficient, for at least acoustic frequencies up to about 50 Hz, 50% to 100% larger than that of an identical chamber entirely characterized by the adiabatic compressibility of air. |

Compositionally modulated zinc-iron multilayered coatings
The present disclosure provides electrolyte solutions for electrodeposition of zinc-iron alloys, methods of forming electrolyte solutions, and methods of electrodepositing zinc-iron alloys. An electrolyte solution for electroplating can include an alkali metal citrate, an alkali metal acetate, a citric acid, and glycine with a metal salt. An electrolyte solution can be formed by dissolving an alkali metal citrate, an alkali metal acetate, a citric acid, and glycine in water or an aqueous solution. Electrodepositing zinc-iron alloys on a substrate can include introducing a cathode and an anode into an electrolyte solution comprising an alkali metal citrate, an alkali metal acetate, a citric acid, and glycine. Electrodepositing can further include passing a current between the cathode and the anode through the electrolyte solution to deposit zinc and iron onto the cathode. |

Electrolysis device
An improved electrolysis system is disclosed in which the tank is designed to operate with a plurality of electrodes that are connected in a parallel plate configuration to a DC power source. The electrode geometry provides a means in which the height of the electrodes is lessened by increasing the length of the electrodes to provide the necessary area for any given current input. The lessened height of the electrode reduces the travel path of the gases escaping to the surface thereby reducing the void fracture height area of the bubbles and increasing the overall system efficiency. Additional efficiencies are obtained with a high surface area of contact between the electrical bus segments and the electrodes. |
