    • The invention relates to micro-resonant devices (MRDs) that generate resonance at radio frequencies not present in an animal or human body, or present at low, background levels in the body. These individual, often monolithic devices, can be located in three-dimensional space and tracked anywhere in a target area, e.g., in a human or animal body, or within a cell within a body, using a conventional magnetic resonance imaging (MRI) scanner or other transducers, e.g., radiofrequency transducers. The MRDs generate high sensitivity contrast in conventional clinical MRI scanners, have a diameter of anywhere from a few nanometers to 1000 microns, and can in some embodiments be manufactured using Micro-Electro-Mechanical Systems (MEMS) technology. The devices are optionally coated to isolate them from the environment, and this coating can be a biocompatible coating for medical and biotechnology uses.
    • 本发明涉及在体内不存在于动物或人体内或存在于体内低背景水平的射频产生共振的微振荡装置(MRD)。 这些单独的,通常是整体的装置可以位于三维空间中,并使用传统的磁共振成像(MRI)扫描仪在目标区域的任何地方(例如在人体或动物体内)或身体内的细胞内进行跟踪 或其他换能器,例如射频换能器。 MRD在常规临床MRI扫描仪中产生高灵敏度对比度,其直径可以从几纳米到1000微米,并且在一些实施例中可以使用微机电系统(MEMS)技术制造。 该装置可选地涂覆以将其与环境隔离,并且该涂层可以是用于医疗和生物技术用途的生物相容性涂层。

    • The present invention generally relates to sensors configured to sense concentrations of nitric oxide. The sensors of the present invention generally comprise a selectively permeable membrane, a semi-permeable reference electrode, and a sensing electrode. The membrane generally comprises a dispersed solid electrolyte. The solid electrolyte generally is a nitric oxide trapping agent configured to stabilize the nitric oxide to form stable, oxidizable nitric oxide complexes. The nitric oxide complexes may then diffuse through the membrane and the reference electrode to the sensing electrode where they are oxidized. An electrical current indicative of the concentration of the nitric oxide generated by the oxidation may be transmitted from the sensor to a picoammeter, which may be configured to measure the electrical current and to signal to a user of the sensor the concentration of the nitric oxide.
    • 本发明一般涉及被配置为感测一氧化氮浓度的传感器。 本发明的传感器通常包括选择性渗透膜,半渗透性参比电极和感测电极。 膜通常包含分散的固体电解质。 固体电解质通常是一氧化氮捕获剂,其被配置为稳定一氧化氮以形成稳定的可氧化的一氧化氮络合物。 一氧化氮复合物然后可以通过膜和参考电极扩散到感测电极,在那里它们被氧化。 指示由氧化产生的一氧化氮浓度的电流可以从传感器传输到皮安表,皮安表可以被配置成测量电流并向传感器的使用者发送一氧化氮的浓度信号。

    • A microelectromechanical vibration isolation system includes a microelectromechanical structure having a plurality of fin apertures etched therethrough, and a plurality of fins each disposed within a respective one of the plurality of fin apertures and spaced apart from the microelectromechanical structure so as to define a fluid gap therebetween. The fluid gap is configured to provide squeeze film damping of vibrations imparted upon the microelectromechanical structure in at least two dimensions. The system further includes a frame surrounding the microelectromechanical structure, and a plurality of springs each coupled to the microelectromechanical structure and to the frame. The plurality of springs is configured to support the micromechanical structure in relation to the frame.
