A micromobility transit vehicle may include a wheel, a dynamo, a control module, and a battery. The dynamo may be associated with the wheel and configured to transmit a first signal based at least on a detection of one or more movements of the wheel that meets or exceeds a threshold movement of the wheel. The control module may be configured to receive the first signal transmitted by the dynamo. The control module may be configured to transmit a second signal upon receiving the first signal from the dynamo. The battery may be configured to receive the second signal transmitted by the control module. The second signal may cause the battery to wake from a battery-off state to a battery-on state.

Wheel movement trigger for battery wake-up systems and methods

Techniques are disclosed for systems and methods associated with free lock detection of a micromobility vehicle. Data from one or more sensors of the micromobility vehicle may be received and compared to a threshold stored or determined for the micromobility vehicle. Based on the comparing, an indication of free locking the micromobility vehicle may be determined and one or more notifications of the indication may be generated and sent for display on a mobile device. A parking condition of the micromobility vehicle may also be determined, such as utilizing image data of the micromobility vehicle. The image data may be analyzed to determine whether the micromobility vehicle is parked within a designated parking area distinguished through distinct coloring, patterns, signs, placards, markers, or images.

Free lock detection of a micromobility transit vehicle systems and methods

Techniques are disclosed for systems and methods associated with locking a micromobility transit vehicle to a stationary object. A multimodal transportation system may include a docking station including a securement point, and a micromobility transit vehicle securable to the securement point of the docking station. The micromobility transit vehicle may include a storage basket and a lock cable including a first end coupled to the storage basket and a second end. The second end of the lock cable may be securable to the securement point of the docking station to lock the micromobility transit vehicle to the docking station. The storage basket may include a pin lock. The pin lock may engage a locking pin of the lock cable to lock the micromobility transit vehicle via the lock cable.

Micromobility transit vehicle lock-to mechanism systems and methods

Systems and methods for determining one or more properties of a sample are disclosed. The systems and methods disclosed can be capable of measuring along multiple locations and can reimage and resolve multiple optical paths within the sample. The system can be configured with one-layer or two-layers of optics suitable for a compact system. The optics can be simplified to reduce the number and complexity of the coated optical surfaces, et al. on effects, manufacturing tolerance stack-up problems, and interference-based spectroscopic errors. The size, number, and placement of the optics can enable multiple simultaneous or non-simultaneous measurements at various locations across and within the sample. Moreover, the systems can be configured with an optical spacer window located between the sample and the optics, and methods to account for changes in optical paths due to inclusion of the optical spacer window are disclosed.

Optical system for reference switching

Methods and systems for measuring one or more properties of a sample are disclosed. The methods and systems can include multiplexing measurements of signals associated with a plurality of wavelengths without adding any signal independent noise and without increasing the total measurement time. One or more levels of encoding, where, in some examples, a level of encoding can be nested within one or more other levels of encoding. Multiplexing can include wavelength, position, and detector state multiplexing. In some examples, SNR can be enhanced by grouping together one or more signals based on one or more properties including, but not limited to, signal intensity, drift properties, optical power detected, wavelength, location within one or more components, material properties of the light sources, and electrical power. In some examples, the system can be configured for optimizing the conditions of each group individually based on the properties of a given group.

Multiplexing and encoding for reference switching

Integrated laser sources emitting multi-wavelengths of light with reduced thermal transients and crosstalk and methods for operating thereof are disclosed. The integrated laser sources can include one or more heaters and a temperature control system to maintain a total thermal load of the gain segment, the heater(s), or both of a given laser to be within a range based on a predetermined target value. The system can include electrical circuitry configured to distribute current to the gain segment, the heater(s), or both. The heater(s) can be located proximate to the gain segment, and the distribution of current can be based on the relative locations. In some examples, the central laser can be heated prior to being activated. In some examples, one or more of the plurality of lasers can operate in a subthreshold operation mode when the laser is not lasing to minimize thermal perturbations to proximate lasers.

A photonic crystal (PC) device including one or more resonant optical structures defined by the photonic crystal structure is affixed to the end face of an optical fiber. The PC device is fabricated on a separate substrate, and then affixed to the fiber end face. This transfer can be facilitated by device templates which are laterally supported by tabs after an undercut etch. The tabs can be designed to break during transfer to the fiber, thereby facilitating transfer. Registration marks and/or the use of device templates having the same diameter as the fiber can be used to provide lateral alignment of the fiber to the resonant optical structures. Such alignment may be needed to provide optical coupling between the fiber and the resonant optical structures.

Optical fibers functionalized with photonic crystal resonant optical structures

An optical fiber is combined with a photonic crystal structure (PCS) that is optically coupled to the optical fiber. The fiber has an exposed fiber surface, and the PCS is affixed to the optical fiber and disposed on or in proximity to the exposed fiber surface. The PCS includes an elongate probe member configured for biological probing. The elongate probe member includes an optical resonant cavity. In an experiment, this was accomplished using an optical fiber tip with a semiconductor template attached to its side face. The semiconductor structure had a thin, needle-like tip (including a nanobeam cavity) which can be suitably inserted inside (or broken off inside) a biological cell without causing cytotoxicity.
