Abstract: Improved cooling systems for handheld devices are disclosed. In some aspects, the cooling system may utilize air inlets disposed behind a guard to prevent debris or liquids from entering the handheld device and potentially causing damage to internal components of the handheld device. In aspects, a vents may be disposed on the guard to divert cooling air into a housing of the handheld device to cool internal components, such as the motor or a printed circuit board (PCB). In additional or alternative aspects, a motor mount may be provided that includes ribs defining air channels to divert or direct cooling air to components to be cooled. The air channels provided by the motor mount may enable the cooling air to reach portions of the internal components that may be distant from the air inlets of the housing.

Abstract: Some aspects provide engineered microbes for glycolate production. Methods for microbe engineering and culturing are also provided herein. Such engineered microbes exhibit greatly enhanced capabilities for glycolate production.

Abstract: Known attempts using engineered bacteria to produce P(3HB-co-4HB) with carbon sources that are structurally unrelated to 4-hydroxybutyrate resulted in relatively low 4HB monomer content of 1.5 to 5 mol %. The current invention provides recombinant hosts for producing P(3HB-co-4HB) wherein the plasmid including succinate semialdehyde dehydrogenase gene (sucD gene) and 4-hydroxybutyrate dehydrogenase gene (4hbD gene) further includes pyruvate decarboxylase promoter (Ppdc). It was found that the 4HB monomer content in P(3HB-co-4HB) is significantly enhanced to be over 20 mol %, in the range of 8.8 to 23 mol %.
