Abstract: The disclosed wearable device systems include several features for alerting and guiding persons who are approaching or near to potentially hazardous or high-risk conditions in their nearby environment. Sensor data from wearable devices (also referred to herein as “wearables”) are used to determine the presence of various unsafe environmental conditions and phenomenon, including dangerous terrain or other unusual conditions. The wearable would be used to warn a person, for example via auditory or haptic-based feedback, if the person is about to encounter an unsafe condition. In particular, the proposed systems can be of great benefit to the visually impaired, those persons with physical disabilities, or persons otherwise vulnerable to particular environmental conditions.

Abstract: A variable optical attenuator (VOA) may include an input collimator with an input fiber connected on one side and an output collimator with an output fiber connected on one side, where the collimators are on a same surface of a VOA enclosure.

The VOA may include an attenuation element positioned between the input collimator and the retroreflector and/or another attenuation element positioned between the retroreflector and the output collimator to provide variable attenuation to the light beam. The attenuation elements may be moved to set an attenuation level by one or more adjustment elements such as a miniature motor. The attenuation element may include a gradient index (GRIN) element, a polarizer, a neutral density filter, or a wavelength tunable filter.

Abstract: A monochromator apparatus for an optical spectrum analyzer may include a diffraction grating, a rotatable oblique prism reflector element with a non-right-angle apex angle, and a mirror. An input optical beam received from an input component may be diffracted by the grating element and reflected by a reflector element, where the reflector element may include a rotatable oblique prism with an apex angle that is different from a right angle. A mirror may reflect the reflected diffracted optical beam back to the reflector element and the grating element. An output optical beam from the grating element may be provided via an output element to a detection element for high resolution optical measurement. The oblique prism reflector element may reduce or eliminate a Littrow ghost effect or secondary ghost effects caused by the grating element.

Abstract: A corporate information technology (IT) network can protect sensitive data sent to computers located outside of the IT network. For example, a customer of a company may control who can access his or her sensitive personal information by identifying his or her access preference included in an access control list, where the access preference describes a level of access that at least one remote employee or person may have to the customer's sensitive personal information. A data protection server may containerize the sensitive personal information and the access control list of the person in a data protection container. If a remote employee or a person requests access the customer's sensitive personal information, the data protection server may perform data protection related operations to provide the sensitive personal information to the remote employee or person.

The system may include a first logarithmic amplifier circuit in a first amplification path, and a linear amplifier circuit and a second logarithmic amplifier circuit coupled in series in a second amplification path. The first and second amplification paths may receive an input signal from a photodiode and provide amplified signals, in parallel, to a selection circuit, which may select one of the outputs of the first and second amplification paths based on one or two power thresholds. The selection circuit may then provide the selected output to a measurement circuit or device. In some examples, the system may also include a sampling circuit to sample the outputs and an analog-digital conversion circuit to digitize the outputs before selection. The power threshold(s) may be determined based on a saturation level of the linear amplifier circuit.
