Abstract:
A gardening box is disclosed. The gardening box may include a main body having a receiving space; a separation board having a plurality of through holes to secure water absorbing units and dividing said receiving space into an upper space and a bottom space; a plurality of observing holes located at a lower portion outside the main body; and a plurality of water absorbing unit secured at the separation board, and a lower portion of the water absorbing unit exposes at the bottom space to absorb water from the bottom space to moisturize soil and plants thereabove. Water level can be observed from the observing holes because the water level of the bottom space is identical to the observing holes according to the law of communicating vases.

Abstract:
Embodiments generally relate to detection of end of service life for respirator filter cartridges for organic vapor(s). Typically, detection of end of service life might use a competitive UV absorbance-fluorescence approach. Thus, a sensor that emits light upon application of UV may be placed within the cartridge, with a UV lamp and a light detector directed at the sensor. In some embodiments, a plurality of corresponding sensor and UV lamp and light detector might be used. Typically, the light level emitted by the sensor(s) might be used to estimate effective end of service life.
Abstract:
Embodiments of close loop optimization of atrio-ventricular (A-V) delay interval and/or inter-ventricular (V-V) timing are disclosed. An implantable medical device includes a housing that supports a processing means adapted for implantation in a patient. There can be two or more electrodes electrically coupled to the processing means where the two or more electrodes can be used for sensing a patient's cardiac signals, which include a far-field EGM. The processing means can determine a width of a P-wave from the sensed far-field EGM. Also included can be a means for delivering an adapted cardiac pacing therapy based upon the width of the P-wave, including revised A-V delay and/or V-V temporal intervals.

Abstract:
A method for making sulfur-graphene composite material is disclosed. In the method, a dispersed solution including a solvent and a plurality of graphene sheets dispersed in the solvent is provided. A sulfur-source chemical compound is dissolved into the dispersed solution to form a mixture. A reactant, according to the sulfur-source chemical compound, is introduced to the mixture. Elemental sulfur is produced on a surface of the plurality of graphene sheets due to a redox reaction between the sulfur-source chemical compound and the reactant, to achieve the sulfur-graphene composite material. The sulfur-graphene composite material is separated from the solvent.
Abstract:
One embodiment of the present invention provides a method for fabricating a group III-V nitride structure with an ohmic-contact layer. The method involves fabricating a group III-V nitride structure with a p-type layer. The method further involves depositing an ohmic-contact layer on the p-type layer without first annealing the p-type layer. The method also involves subsequently annealing the p-type layer and the ohmic-contact layer in an annealing chamber at a predetermined temperature for a predetermined period of time, thereby reducing the resistivity of the p-type layer and the ohmic contact in a single annealing process.
